    40k TT

    So I'm looking into going to the NC state TT championships, and thinking of taking the fixie since theres only 500ft of elevation gain for the course.

    But I'm curious about gearing, I gear myself according to the speed I want to average and the cadence I want. So does anybody have any times for a mostly flat cat 4 40k tt. I know its a lot to ask but whats a good time and or average speed I would need to win?

    I cant seem to find any cat 4 40k tt times.

    New Bern is a freakin FAST area.

    Last year the 3/4 RR was rolling at +/- 27-29mph for about 60 miles, and was easily the least painful race I did that year. The winning 20k TT times were at around 27mph I believe. I'd therefore imagine a good 40k time might be 25-26mph...

    Ride at 29.318 mph in a 53-18. Use your TT bike. Take off the small chain ring.

    Yeah I'm realizing its going to be a lot faster than I thought, I guess it will be a time for good old 52*15.

    ummmmm...

    I think I will ride a harder gear then that, My leg speed sucks this year, but it would be impressive to average 125rpms for the entire TT.

    Cat 4 TT championship in Florida last year was won in 54:29. Breaking the hour got you in the top ten.

    Provincials TT I did 53:45 over 38.5 km and came 5th in Cat 4. But the results in the lower cats can be skewed due to the participation of elite triathletes (who are often in cat 4/5 on the road). In a flat 40k, if you can hold around 42 km/h, you should do well as a Cat 4.

    Assuming I can work out a couple of scheduling issues, I'll be at the NC State TT as a Cat4 as well. Things to consider when comparing times with other areas are:

    - Flatness. The NC championship course will indeed be flat which leads to fast times.

    - Altitude. Being at sea-level is a significant aerodynamic disadvantage compared to, say, 5000 feet.

    - Road conditions. I have no idea how good/bad the roads are but they're not going to be as good as Lowe's Motorspeedway.

    - Number of turns. As far as I can tell, there's one turnaround at the halfway point. That means faster times.

    - Wind. This is the wildcard, of course, but I think we can expect wind to play a significant role in the NC Championship TT. I would expect times to be about 3-4 mph faster on the out leg than the back leg. This is the only area in which having a fixed gear bike will put you at a disadvantage compared to everyone else.

    I would guess that the winning Cat4 time is somewhere in the 56 minute range.

    Check this out...http://www.ncnca.org/road/2005/DistTTResults.html. They are held on a flat course near Lake Tahoe at 5000 feet.

    Is a fixie legal? I thought that the bike had to freewheel.
    Reacting is mind candy; it requires no thought. Thinking is tedious.

    I dont think so, I think it just has to have two brakes. I sent an email to a USCF official friend of mine to find out the exact legalities of a fixie, that I could put in the face of officials at a race if need be.

    I don't think anyone would even notice.

    From the USCF handbook.
