Time Trial Preparation

As I’ve mentioned quite a few times on the blog, there is a lot more to a fast TT than pedaling hard.  Back in 2010 I was tearing up the Cat 3 fields, riding away in criteriums and putting down some of the highest wattages I’ve ever seen on flat ground.  I slapped some clip-on aerobars on my road bike and went out with hopes of winning the Cat 3 State TT.

I didn’t.  I finished a dismal 14th.  I was passed by numerous riders.  Even my power was startlingly low that day.  I learned that there is a lot more to a good TT than having a Time Trialists power profile alone.  The TT has been a multi year-project for me, one that is still in progress.

Position

I’ve done what I can to find a good position.  I’ve worked with the equipment I have available and my power meter to find a position that ‘looks’ fast to me, and that I can achieve good power numbers and race results.

One method I’ve used is filming myself.  If you’re a bachelor, this might not be too hard since you can do it in the privacy of your own home (or garage… no windows).  Otherwise, take your lumps from your family and setup your trainer where you can videotape yourself from profile and front views.  Ideally find a way to put the side view of yourself on screen in front of you.  Wear your TT helmet and look at obvious areas for improvement.  The helmet tail should lay close to the back, and your head should be low.  Try a few stems, risers, spacers, and aerobar angles to see what feels comfortable.

Modifications to equipment are often necessary.  I modified and reconfigured my helmet straps and retention system so my helmet can lay at the ideal angle.  I modified my aerobar pad risers, and even modified my aero bottle mount for ideal position.

The next step for me will probably to see a professional time trial bike fitter.  They know many riders who have been to the wind tunnel, and have seen their results.  They also understand bio-mechanics and can help refine position without the cost of a visit to a wind tunnel.

MacGuyver-ing

Hopefully if you’re a cyclist, part of your enjoyment of the sport is the equipment itself.  I enjoy working on mechanical things and do almost all of my own bike work.  This is even more important for time trial equipment, which must be fit to the rider and budget.  If you pay close attention to ‘pro bike’ profiles of top professionals, you will see many more do-it-yourself modifications and non-sponsor correct equipment on time trial bikes for exactly this reason.  Luckily I enjoy this aspect of preparation for the time trial as much as the training.

Looking Ahead

I was hoping to give a profile this week of my bike for this year’s race, but I didn’t quite find the time to take the photos.  The State Time Trial is Saturday, less than 48 hours away.  After the weekend’s race reports, I’ll post a profile of my bike and detail my efforts to find all the speed I can.

    Good luck!

    as well as getting a good position how much time do you spend training in that position to get used to it and make sure you can put the power down?

      My goal this season has been to ride on the TT bike once per week.

      I’ve come pretty close to that, and been on nearly twice per week the last month.

      I’ve also done a couple 100k rides, quite a bit longer than the 40k race.

    Russel, you can actually get a really good estimate of how “aero” your position is by using Robert Chung’s regression method. Lots of people (seemingly) have determined it to be pretty close to actual wind tunnel testing. Like most things, the accuracy will depend on how much effort you put into making it accurate.

      I’ve thought about doing ‘roll down’ or runs on a flat stretch of road early in the morning with power / etc.

      At this point I just haven’t had the time to devote to taking the data. For now I’ve been relying on power numbers and race results as my guide. Perhaps for next year I will make this part of my preparation. There is also a new outdoor velodrome being built and I’m hoping they’ll open it to geared bikes for aero testing now and again.

      It is a good idea and you’re right to suggest it.
