Pacing a Time Trial using Power and Perceived Exertion




by Gary Tingley -

The ability to pace a time trial correctly is a challenging yet essential skill for a competitive time trial cyclist to master. For flat and low wind time trial races of durations between 10 miles and 40 kilometers, I often break the event into four parts:

1. The start. Rolling a good start will lay the foundation for a confident race. With five minutes to go you head over to the start area and take your position in line. You spin the cranks forward and ensure that you are in the correct gear. Your cycling computer is ready to record. You are hydrated, rested, warmed up and ready to compete. Close your eyes and picture yourself on the podium. Draw a mental picture of yourself rolling across the finish line as you clock a new personal best time. Find your motivation and remember it for later. After climbing up to the start house, or the start line, ensure that you have shifted to a large enough gear that will allow you to start out of the saddle and power up to speed for 10 seconds. At 1 minute out from your start, hit your timer. Take a few calm deep breaths and prepare for the countdown. Go.

2. The first five minutes. This is one of the most critical sections of the race and pacing this section correctly can mean the difference between correctly pacing your best effort and blowing midway through the event. Pacing with a power meter can be invaluable during these first minutes. Your power during this period should put you in the range of 95% of your projected average power for the race. After the five minutes you should take inventory on your perceived exertion as compared to actual power, and adjust as needed for the day. Not everything is black and white when it comes to pacing with power. Use your power meter as a gauge, deferring to your perceived exertion. Listen to your breathing, focus on a smooth cadence. Push it.

3. Out to the turn-around. After the first five minutes of the event and after you have settled in to a strong sustainable rhythm, try to ramp it up a little harder and keep yourself focused on riding the razor’s edge. This period of the race is very challenging to pace, as you are still relatively fresh yet you may have doubts about your starting pace and your ability to keep your current pace up for the duration.

4. The return leg to the finish. This is the "perceived longest" and most challenging section of the race. This is the section where you make deals with yourself in order to finish strong. “Just steady to the next mile marker” … “ok, keep this effort until you pass the next rider”. This is where the hours of intervals and time spent training and racing on your TT bike will pay dividends. Metering is done by perceived exertion using your power meter as an additional gauge. Your comfort during this section of the course can also play into how focused you are on putting out as much power as you possibly can. You may find yourself shifting around on the saddle, or unable to hold your position. You will have to dig deep into your well of confidence. Remember your motivation.

Racing a course that has rolling climbs can necessitate a slightly different strategy. Pushing (a little) harder on the climbs, and letting off (a little) on the descent can prove to be a faster strategy than to iso pace the rolling event. In contrast, I prefer to pace evenly or just slightly harder into a headwind and either even or slightly easier with a tailwind, providing that I am riding directly into the headwind. Pacing a time trial is an acquired skill, one that will likely take you several events to master. Using your power meter to pace in training is an excellent method of calibrating your perceived exertion for race day.

40 Minute Time Trial Warm-up




by Gary Tingley -


I have used the same warm-up protocol for the past several years with success. The key is to properly prepare for the race while remaining rested, relaxed, and by staying cool. The warm-up is 40 minutes total, completed on a trainer or on rollers.


  • 20 minutes easy spin, slowly raising cadence to 100 rpm, and include a few 5 second high-cadence bursts, then
  • 1x4 minutes @ 90%/95%/100% of FTP w/2 minutes easy spin between intervals 1-2, 2-3, then after interval 3
  • 4 minutes easy spin

Roll over to the start area with 10
minutes
to go.

Faster Time Trial Turnarounds

by Gary Tingley -

"Every second counts" and efficient time trial turnarounds can lead to quicker TT times. Practicing turnarounds can also lead to more confident bike handling. In the off season I practice the following routine on a closed street with a road cone. I've found that the fastest way to navigate a turnaround is to
  1. Approach the turnaround as far to the right of the course as you can ride
  2. Keep your speed up until the very last moment
  3. Shift up two or three cogs, then sit up and get on the brake hoods
  4. Brake, pass the cone by one meter, look over your left shoulder, then begin to corner
  5. Scrub just enough speed to corner and take a tight line with the cone on your left
  6. Sprint back up to speed, out of the saddle
  7. Get back up to speed quickly and then get back into the aerobars
  8. Shift down and quickly settle into your TT pace

Faster Triathlon Bike Splits Through Time Trial Racing



by Gary Tingley -

The bike leg of triathlon and duathlon is essentially a time trial race sandwiched in between swimming and running. You will find subtle differences in training for a true time trial race, such as frequency, duration, and other TT specific workouts.

Here are a few tips for your first time trial:

* If preparing for an upcoming event, use the race as training, race the time trial using all equipment you will have with you during a tri - spares and water - this way you "train like you race".

* Wear a jersey that covers your shoulders, many USCF races require this.

* You may be required to purchase a 1-day license at the event.

* Warm up for the race for at least 45 minutes incorporating 'step' intervals that prepare your body for high race efforts. Consume some CHO drink.

* At the starting line a 'holder' will hold your bike saddle (at most events) and allow you to clip in to your pedals. Start your stopwatch when the rider in front of you goes off - then subtract the time difference when you finish (depending on the race, usually 30 seconds).

* You will want to start the race on your non-primary leg (your weaker leg) which will allow you to power a full revolution of your more powerful leg once you start the event. Make sure you are in the correct gear, spin your cranks forward and backward before you line up to make certain that your chain will not drop. Take a few deep breaths right before the start, then when the official says "GO!" (on the basebar) shift your weight forward and push hard, sprint up to speed (10 seconds) and settle into your pace.

* Don't worry about keeping a set heart rate or power during the first five minutes of the race, instead try to maintain a pace just under your 1-hour race effort. After the first five minutes you will want to hold your power or heart rate just below or right at your 1-hour threshold power/pace, then bump it up and really give it your all in the last 1/3 of the race. Focus on finishing strong.

* Depending on the course profile, finish the race with the same power and a higher perceived intensity that you started it with, but have nothing left to give at the end of the event. If the profile is hilly, you will want to push a little harder on the climbs.

* Properly warm down and stretch to prevent injuries. Hydrate and get some CHO drink into your system.

Time trial racing is one of the best ways to improve your bike split. You already have the bike and the fitness, all you need to do is show up and race a TT!

Top-10 Cycling Recovery Tips


by Gary Tingley -

Recovery is undoubtedly one of the most important aspects of a well rounded training program for the competitive cyclist. Day and day out training, work, home, and life stresses can increase the fatigue that a rider experiences throughout the day, and can minimize the effectiveness of the workouts performed. To realize the most of your training program, effective recovery techniques can lessen the stresses of daily life and can help to prepare you for the next day's workout.

Compression clothing can help office workers, travelers, and those who spend considerable amounts of time standing throughout the day. Mid-day stretching and "sunshine breaks" can also assist with reducing stress in the workplace. A healthy diet and ample vitamin supplementation are important foundations for a sound training program.

1. Nutrition – replace glycogen with a sports drink within 30mins-2hrs post ride at the rate of 1.5g carbohydrate per kilogram of body weight per hour for up to 4 hours. I prefer a bottle of Fluid, a Coke or bottle of Cytomax.

2. Clean up – shower, or after a race/training ride where I cannot immediately shower, I’ll use a few baby wipes to clean up.

3. Baby powder – keeps things dry.

4. Nap – a short 20-30min lunchtime/afternoon nap can be beneficial.

5. Stretching – improves mobility, flexibility, eliminates stiffness.

6. Massage and Compression socks – massage is worth it if you need work done. Also, “the Stick” and Foam roller work well.

7. Ice – if I am feeling particularly sore, I’ll ice my joints and/or muscles immediately after a ride.

8. Hydrotherapy – a warm bath can work wonders for a sore body (however, not immediately following a workout).

9. NSAIDS – Advil/etc. can help with pain, but use sparingly and as directed by your doctor, stomach ulcers and other risks are involved.

10. Sleep – aim for 8 hours per night, no more than 9, no less than 7.5 ~

Time Trial Pre Race Day Prep





by Gary Tingley -

It's the day before the big event, and you are wondering "should I take it easy today?" Yes, absolutely. One of the most important race preparation elements is relaxation. You should arrive at the event relaxed and prepared to give your best effort.

How to best prepare yourself depends on where you are starting from and the type of event you are competing in. There are a few basic preparation tasks that I use for time trial races (can also be used for triathlon):


1. Prep ride warm up. I'll use the same 40 minute warm-up the day before the event as I do on race day, and if I can I will ride the actual race course. The goal here is to blow out the cobwebs while staying relaxed and fresh.

2. Confidence and mental rehearsal. If this is a new course, or a championship event, completing a pre ride the day before on the actual course will give you confidence to corner at the maximum possible speed, and will allow you to observe the course profile and any potential hazards. Practice mental rehearsal of a strong start, smooth turnaround, and solid finish. Visualize yourself pedaling smoothly with relaxed breathing.

3. Nutrition and sleep. I tend to keep nutrition simple and stick to my normal diet. I will not restrict calories the day before a race and I tend to avoid heavy foods that may cause digestive problems. Since many events begin in the morning, it is important to turn in early to prevent unnecessary fatigue. I strive to get 7.5 to 8 hours of sleep the night before the event.

These are but a few of the numerous little items that truly add up on race day. The goal is to line up the day of the event in the most rested and best prepared condition possible.

Aerodynamics for Time Trial Racing


by Gary Tingley
-

My first time trial was ten years ago at a Fiesta Island TT. I rode a Specialized M4 road bike with Spinergy Rev-X wheels and clip on aerobars. Coming from a cross-country mountain bike background, and having dabbled in multisport events the previous year, I assumed that racing and training for a time trial would be "easy" compared to MTB events. I quickly learned that the sport of time trial racing is highly technical, and it can take years to develop optimal fitness and the skills needed to excel in this discipline. In the following article, I will discuss some of the finer points of basic time trial aerodynamics I have picked up along the way, and the priorities one should consider when upgrading equipment.


I often get asked the question about where to invest upgrade dollars when considering new equipment and gear. From results others have shared with me, my time in the wind tunnel observing athletes, and the various data reports that I have read, I will offer the following list of priorities for a time trial bicycle and the rider. This evaluation is fully debatable and represents only my opinion. The results below were gained from various sources and in most cases represent a rider at 30MPH at zero degree yaw over a 40K course.

** Maximum time savings for these upgrades over 40K:

Aero Wheels - Using aero wheels (vs. 32 spoke box rim wheels) can save you two minutes over a 40K time trial. The fastest wheels are a deep dish front (Zipp 1080, Zipp 808, Stinger 9, HED H3) paired with a disc rear (Zipp, Bontrager, Mavic, HED). Aero wheels definitely make a substantial difference in reducing aerodynamic drag. When deciding which wheels to purchase, HED makes a yaw calculator and Zipp has aero test results to help you in your decision.

Aerobars - Aerobars are the #1 most important feature of any time trial bicycle. Integrated one-piece aerobars are more aerodynamic than clip on bars. Wind tunnel tests show that using aerobars can save 4 minutes over a 40K time trial course. Currently there is an abundance of aerobars on the market, and the fastest aerobars carry the labels of Profile Design, Zipp, Bontrager, HED and Vision Tech. These new one-piece units are some of the best designed and likely the most aerodynamic aerobars made today. For clip on aerobars, the classic Syntace C2 (a triathlon favorite) has been moved aside by Zipp and Vision Tech base bar and clip on bar systems.

Aero Frames - Many frames on the market claim to be aero. The most important feature that a frame can offer you is the fit, followed by aerodynamics, stiffness and comfort. Many new aero frames are designed around UCI rules. This requires a double-diamond design, and 3:1 tubing aspect ratio. If racing national championship events you should consider a UCI legal frameset. Frame aerodynamics are important, however fit is even more so. When selecting a frame, fit and comfort are paramount considerations. How do you know if the frame you are considering is aero? Start with the tubeshapes of the bicycle. Are the tubes airfoil shaped? Is the downtube narrow and deep? Is there a closely spaced rear wheel cut-out? Aero seatpost? These are some items to consider. Some of the top companies today that produce aero time trial frames are (in no particular order) Specialized, Cervelo, Trek, Orbea, Kestrel, Felt, Softride, Corima, Lotus, Elite, Quintana Roo, Aegis, Pinarello and Colnago.

Conclusion – Aerodynamic gear does not come cheap, so keep these two points in mind when considering upgrading your equipment:

  • Buy the fastest gear you can afford, but remember that position on the bike is paramount to anything you bolt onto it
  • Buy an aero helmet first, then a skinsuit, then upgrade your wheels, then the frame

Wind Tunnel Aero Test Results for Time Trial Helmets and Hand Positions


by Gary Tingley -

We tested several aero helmets. Not surprisingly, we found that every athlete responds differently to aero equipment. One common theme is that there were "good" and "bad" helmets, regardless of the rider that was testing them. Results for the Louis Garneau and Giro are shown above. Surprisingly, the old Troxel titanium dimpled helmet also tested well.

  • Lower profile helmets are more aerodynamic
  • Shape matters, the helmet should transition to the rider's back as seamlessly as possible
  • Visors were not tested - may or may not have an impact
  • "Filled" tails were not tested - again, may have an impact especially for tails that sit up off the back





We also tested three hand positions, the "pointer", "pistol", and "superman". What was apparent is that there were little discernible differences in the results, with the best result from the original baseline "pointer" position. This is likely due to the smaller frontal area that the position provides, as compared to the other two positions.


  • All three hand positions are fairly close in terms of aerodynamics
  • Gloves were not tested, however if gloves were to be worn, a low profile set such as the aero versions from Castelli or Nike should be considered
  • Smaller hand profiles are important

How to Calculate your Aerodynamic Drag using a Power Meter



By Gary Tingley

Using details in the screenshot above, and the calculator provided by Analytic Cycling, you can estimate the power required to complete a time trial for any specific time. In the example screen shot above, I used a 20k time trial at sea level on a calm day. An alternative method for estimating aerodynamic drag can be found by measuring anthropometric data.

The calculators and links required are located at:


For this example, rolling resistance for the course is in the numbers in the screen shot. For purposes of the estimate, use the defaults in the image for pedal range, wind, drag, air pressure, Crr, and rise.

Then plug in your crank length and average cadence.

Also plug in the speed in meters per second, then change the frontal area up or down until the power matches the average from the race, with the caveat of the time lost to inertia at the start (add 5 seconds to the time).

An example for a hypothetical "aero-tuned" cyclist competing at the Fiesta Island Time Trial in San Diego, California, which is a point to point 3-lap 20k course:

.44 frontal area [.440m^2 x 0.5 = .220m^2 of CdA]
83kg rider and bike Slope – 0.0015, crr 0.004, 12.69 m/s – 332w – 26:15 for 20k
+ 5 secs first lap = 26:20

.44 frontal area [.440m^2 x 0.5 = .220m^2 of CdA]
83kg rider and bike Slope – 0.0015, crr 0.004, 12.82 m/s – 341w – 26:00 for 20k
+ 5 secs first lap = 26:05

Once you know your CdA, you can calculate your Functional Threshold Power (FTP) as it relates to your aerodynamic drag (CdA) in terms of W/m^2. With this number you can then compare your aerodynamic drag/power ratio to other riders.

GERARD VROOMEN - Co-Founder of Cervelo

Consumers often complain they can’t verify aero claims made by manufacturers. True, unless you have a windtunnel in your backyard.

But you can use the laws of probability and common sense to set the minimum level by which a bike manufacturer would lie about its models’ aerodynamics. Here is now:

Bike manufacturers make claims on weight and on aerodynamics.
The first you can verify, the second you can not.
Therefore I would venture that they will be no more honest about their aero claims than they will be about their weight claims.
Makes sense, doesn’t it? If they lie 10% about a claim you can verify, do you really expect them to lie less about a claim you can’t check? So get out those scales and go weigh some aerodynamics!
