(Originally written in 2009)
My first time trial was nine 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.

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

5 Early Season Race Prep Indoor Workouts
in Uncategorized/by Gary TingleyIn many parts of the U.S., early season racing will soon be upon us. Get tuned up with these indoor race-specific workouts. I perform these on my SportCrafters Omnium Trainer and use a large floor fan for cooling. Note: For pacing using PE or a HRM, see Power Training Levels by Training Peaks.
More at http://socalcycling.com/2014/12/27/training-early-season-criterium-race-prep-workouts-gary-tingley/ and https://www.sportcrafters.com/blog/5-early-season-race-prep-indoor-workouts
#1 – High Cadence/High Intensity Surges (1.5 hour ride)
Start with a 20-30 minute gradual warm-up.
For this workout, visualize taking :15 second HARD (130-150% FTP) pulls, and then dropping back behind an imaginary breakaway partner into the draft for :15 seconds. Do this for 10:00. It will be difficult, but keep it rolling. Then easy for 5:00.
Finish out the ride at endurance pace (70-80% FTP).
#2 – Threshold Intervals (1.5 hour ride)
Begin with a solid 20+ minute warm up, stretch out the legs.
For main set #1, ride 4 x 12:00 @ 98-103% of your FTP with a 3:00 rest interval between each threshold interval.
Cool down for 10 minutes.
#3 – Climb the Pyramid (1.5 – 2 hour ride)
Warm up for 20:00.
Then do a reverse pyramid of intervals @ 93-95% FTP, starting with 20:00 and working your way down, by cutting the time in half: This is 20:00; 10:00, 5:00, 2:30; 1:15; :45. Incorporate 3:00 of recovery time in between each effort.
Recover for 5:00+ after the last interval, to make 1.5-2 hours total ride time depending on your needs.
#4 – Bursts and Sprints (1.5 hour ride)
Warm up for at least 20:00
Then complete a set of 5 microbursts of :30sec/:30sec 150% of FTP “ON” and 50% of your FTP “EASY”. Then ride very light for 10:00 to fully recover.
Then complete 3 “full gas” sprints from a slow roll/stop, full effort :10 to :12 second sprints with 4:00 of full recovery between each one. For the sprints, jump hard out of the saddle, explosive effort to get on top of the gear, then when you have reached maximum cadence, sit down and maintain maximum intensity for the entire length of the effort of :10 seconds or 20 pedal strokes.
Then after this set, ride at endurance pace to make 1.5 hours total ride time today.
#5 – Race Day Pre-Race Warm Up (40 minute ride)
The warm-up is 40 minutes total, and at a race is also 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 1×3 minutes @ 90%/95%/100% of FTP w/2:00 easy spin between intervals 1-2, 2-3.
After interval 3, 4 minutes easy spin
Roll over to the start line area with 10 minutes to go.
Faster Triathlon using Time Trial Races for Training
in Racing/by Gary TingleyThe 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:
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!
