My first TT

My first TT

Postby snedden9485 » Sat May 23, 2009 8:17 pm

Done my first 20 km TT today. The course was 10km, so 2 laps of a hilly course. No major hills, but some nice undulations and a decent surface. It was really windy and overcast, on the brink of raining the whole time, but it didnt thankfully. Wind was strong and generally a hard cross wind. I rode my cervelo with full road set up. Was nice to see all the A graders with TT bikes and skinsuits / aero helmets etc.

I used the guide set out in my previous post, which went pretty well, i didnt blow at all and felt good for most of the race. I kept the HR between the 88 - 95% Max hr for the majority of the race and was concious not to get over the 95% HR. My heart felt good, but the legs werent too strong for the race. I think i went out a little easy on the first lap, as the guy behind my caught me at the end of the 1st lap, but i sat at a constant gap behind him once he passed me quite easily. So, i think i should have went out harder at first, but it was my first ever TT (iv never even rode one in training).

My time ended up being 34min 17 seconds, with an avg speed of 34 km/h from memory. Pretty happy with the result, as it was very windy and its a pretty hilly course. The A graders with full aero set ups were doing times of around 31 minutes, some riders doing a little faster. So for my D grade arse to do that time with no tri bars or anything, is pretty good for the confidence.

I really enjoyed the race, cant wait to start doing some TTs for training and seeing what times i can put out.

Going to put some tri bars on the cervelo. I think i can make it a decent TT bike with the adjustable seat angle and full aero frame. What other things should i look at for future TTs in terms of set up? I have heard the helmet makes a big difference, but dont think il rock up in one of them till im in the higher grades. :P

Skinsuit. Cheaper than an aero lid and probably more effective. I wouldn't get too concerned about not being fast enough for your equipment (but time trial problems are best addressed in the engine room :wink: )

And don't start too hard. When perfectly paced, the first 5 mins should really be keeping yourself from opening the taps up from what feels like a tempo effort, so sounds like you done well.
Congrats.

Running around 90-95% of max heart rate is pretty impressive,only 3 minutes off top time says something?...I would think TT bars would be a pain unless that is all you are going to do...take a bit of changing over.Maybee clip ons?.Never done a TT...but there are a few (4 or 5) at the end of the season....but going off the bike porn I race against every weekend I am pretty sure they will all be on specific TT rigs as well.

Yeah next time il definately have some TT bars as a minimum and proly some aero oversocks. Cant wait to start doing some TT training on the course and see what sort of times i can put out. As a guide, what sort of cadence is good for a TT? I was under the impression a cadence of around 110 is a good TT cadence? I would say may normal cadence is around the 95 - 100 mark generally.

Your normal cadence is a good TT cadence.

Wish I could keep an AVS of 25 km/h let alone 34! :shock:

Going by your race reports I would have thought tts would be what you are suited to, lots of off the front efforts pushing big gears. Cervelo P2C's aren't that expensive.... :)

Yes I have always thought I would go OK in TT's...and my power results certainly seem to point that way.But like a previous post of Ant's...he put out 50w more on his roadbike than on his TT bike but still did the same time...so unless I am on a TT rig I am going to struggle...like I said there will be guys on bikes good enough to ride the TDF on... :roll:
But I was wondering if you had descent clip ons,bottie covers,maybe a rear wheel cover,I can't get a skinsuit because I can only race in club kit and I can only order once a year...how much will I be losing to someone on a TT bike?...roughly.
Either way I am going to give it a go...1st one on the 30 Aug (20km) ..should be able to hold 380 watts for 20min :wink: :D

I had my road bike set up with clip ons and the seat 5cm behind the bottom bracket although not aero wheels. I go about a minute 20 faster over 20 km on my tt bike albeit with deep dish carbon wheels also. Not sure how much of that is in the wheels though. TT's have become pretty popular in our club over the last 12 months and every one is getting somewhere around 30 secs improvemet per 8 km lap on our tt course when they get a tt bike. The ones who haven't been using clip ons get a fair bit more than that.

Go with some clip ons at least, they seem to relax your upper body so you can concentrate on your legs and make a big improvement by themselves. You'll be hooked after your first few and getting a tt bike anyway. It's great watching the riders in front and trying to reel them in, something you'll be doing plenty of 8)

You'll do some serious demolishing at 380W.
Today, I was 20-25s faster (official numbers not released just yet) over 20km, same course/road-bike/position as before, but with an aero helmet, zipp 808front/sub9 disc combo, instead of road helmet and 303front/404 rear. Oh, and I pushed out 25W less than last time (long story... bit of a sore point with me right now actually, involving saddle height advice/changing which proved to be a great idea :roll: ).

I wish I pushed 280W again so I could say (for me) exactly how much quicker TT wheels and a helmet are, but even at 9% less power pushed, they're still maybe 45s quicker over a 40km distance. Analytical Cycling isn't working for me right now so can't extrapolate time savings had I pushed my normal power numbers.

I could definately hold the wattage for 20mins...probably a bit more if motivated enough.But my aero body will suck all that up in drag :lol: ...I will get some bars or clip ons thou...have been wanting to try them for a while.
Look I would invest a lot more in aero parts but as nothing seems to last more than 6 months..I have enough trouble keeping my road bike rideable!.Also I am not sure if there is a ATTA similar organisation in this area...would be a lot of money for just 2 or 3 races a year.Doesn't stop most people here thou....I do love ogling the bike porn at Sunday Races.The last time my club ran a TT there were at least 2 Olympic Special Cervelo TT bikes...problem was they had Olympic riders on them destroying everyone!.
It seems the TT scene is having a ressurgence in OZ at the moment?.
By the way you have some seriously nice bits listed there Ant!.

So Ant,

your point in short is the TT set up makes quite a difference. I am looking at slapping some TT bars on the cervelo and wearing some aero socks for the next TT. Think the aero bars would be a big difference at least.
