Time trial ????

Recommended Posts

I want to do the GNC time trial this year, and not only the road race as previous years, if it goes OK I will do the double at SA's as well.

 

Got myself a nice pair of tri-bars I will test out on Sunday's harties ride, so we will see how it goes.

 

A few questions to the seasoned TT specialists out there:

 

I am 1.67 and weigh 70kg's and a Vet. Max HR is 200, and I can sustain 180-185 easily, although my threshold is at about 165-170. Now, how many watts as a rule of thumb should I be able to sustain over say a 35km TT at 180-185 to do a decent TT performance?

 

Bikemax, 101%, etc. whats your take on this?

Michelle thats 5.7watts per kg!!Do you want the guy to stop cyclingLOL

From what I understand 5watts per kg would be considered a very good power level for a VETs rider.So somewhere close to 350 watts should do the job ,but as far as I know there are very few VETS on this level!!

nochain: I'd consider that a decent TT performance.. wouldn't you? LOL

Hi nochain.

 

I would think around 400W is ideal for a good result.

The trick with TTing is to be able to sit , concentrate and keep a smooth yet powerfull pedal stroke for around 40min's. It doesn't sound like a long time but to be able to ride at 100% for that period of time with full concentratiion takes alot of practice.

 

Ive started this week with riding my TT bike for at least 3 sesions out of 6 aweek which averages about 7 hours or roughly 220km's a weekDead...

I think 400watts is a touch optimistic if you weigh 70kg's.  Landis did 396watts in the final TT of the tour last year and he weighs 68kg (56 minutes I think), and he was one of the fastest for that TT.

 

Top vet's in the country are around 5w/kg functional threshold, so at your weight this would equate to 350watts.  40km TT will take approx 1 hour so your performance will be governed by your functional threshold power.

Shew 400 is very good! But yeah Michele that would be ideal!

 

BikeMax will know for sure, but i am a little taller than you (1,75m) and i weighed 72kg 3 weeks ago, dont ask what i weigh now (chocolates Embarrassed) and i could average around 267 watts for 20 minutes on the cycle ops bikes (hard bikes). I think i might have gotten a bit stronger since then but not too much. I am a below avg vet rider in CT but usually raise my game in road races so i perform better than my tests show. A little self belief thing i got going LOL

 

I reckon if u can get up to averaging around 4 watts per kg for Bout 10 mins, ur in a good place and should be reasonably competitive for vets.

 

I was almost there around the argus this year and was climbing quite well. I think i could manage 300 watts for 10 mins (3-4 intervals) at a weight of 73-74kg, putting me at  4.05 watts/kg. I didn't do a great argus (safety concerns - rode at the back and it cost me time) but i know i was climbing better than ever at that power - weight ratio.

 

So i reckon aim for that figure if you aren't already there, but i think you might be strong enough already Tongue

 

But see what Bikemax says, he knows his stuff.

Bruce ,how big a difference would frontal drag of say a 70kg versus that of a 78kg rider for instance make?

The reason I am asking this is that if the TT is flat ,like the Sa's for instance.would a rider at 350watts/70kg at all be able to compete with a guy that sit at say 400watts,nevermind someone that weighs say 65kg and only produces 325.It sounds to me as if the guy at 65kg should rather stay at home and focus on the road race than try and compete in the TT with guys like 101%LOL

[/quote'] So you saying 101% is heavy? LOL

I should hope that if he is at 400watts he at least weighs 78kg's!!Dead

I think they should make a rule that if a VETS rider goes above 5.2watts per kg he has to race elite!!LOL

How do you decode that chart? Based on your performance, what is the formula they use to get to those numbers?

How many watts you push for that time duration / your weight
