attachable aerobars? waterbottle mounts? pacing?ishmael

Im planning on doing the Pennsylvania state timetrial which is totally new to me (the other timetrial I did was only a steep kilometer and a half). This course is 40km and supposedly hilly but keeping in the big ring. I was thinking of getting some attachable aerobars but I'm not sure if it's worth it for the course or what would be best. I've never used them before but wanted something simple and cheap if at all. What about spinachi or something I saw that was diamond shaped. Should I just use my normal water bottle mounts, I'd rather. I heard the bottles on the back of the seat were less aero anyway? How much water for a hilly 40km? Any pacing advice? I dont want to get a heart monitor(seems like a hinderance anyway) and I dont have a computer. Should I just go as fast as I can and see what happends? I think thats whats going to happend anyway. I was hopeing that I'd be able to see who was in front of me so I'd have someone to hunt down, thats always motivating. I forget when or who it was but someone in the tour de france said they had a great performance while alternating effort in their legs. He would put more effort into a leg for 3 revolutions and then switch. Kind of mindless but maybe thats good. Concentrating on the pain is supposedly a good idea instead of trying to ignore it(read that on here somewhere). Any insight? If I start seeing stars and going dizzy I should slow down huh? Know anything abou the PA state course?

See http://www.analyticcycling.com/RiderAeroStudy.html for water bottle question. It is an advantage during a TT to leave your normal water bottle mounts instead of placing the bottles behind the seat. Most of the advanced TT'ers seem to use 1 large bottle during a 40km.

I just did my first TT (40km) as a CAT5 and my local shop (a race oriented shop with plenty of experience) recommended against aerobars until I become more advanced/complete more races. Depends on your level. If the course is hilly, it may be less of an advantage to have them as a beginner - but I'll let the more experienced folks answer that and your other questions. Good luck.
well, depends on the framescc

Your link is from a test by John Cobb, but it is really frameset dependant, for more information click here (more from Cobb): http://xtri.com/article.asp?id=608&offset=2

"Ill leave you with two final tips. If you have a look at my position then you will see that I dont have any bottle cages mounted. I asked John for his opinion on the ideal set-up for me. Best of all is a CamelBak but if I had to mount cages then behind the seat is superior to on the frame (for my bike). John also mentioned that the best rear mount systems are those that leave the bottles low and behind the legs. We didn’t discuss brand names, but I know one popular brand that leaves the bottles sitting high and exposed to the wind leaving the riders back (not good at all)."

Get aero bars, at 25 mph, more than 75% of your cycling effort goes to overcome wind resistance. If you plan on just using them for a few time see if you can borrow someone else's bars. Practice with them first several times.

Training: it is all about being able to maintain 85-90% MHR, or just below LT, spinning a 80-90 rpm gear while seated, and remaining in the aero tuck for an hour. Make sure you stretch and are very flexible in the position. How long can you ride in the aero position? If not fitted right and your saddle "numbs" you it may only be a short time. I ride 2 hours in the aero position at 80% MHR for the whole time once a week, w/o getting on the pursuit bars, it is important to get the feel and comfort there.

Time trialing is a specialist sport and you must train it to get good at it.

I've only done a couple of TTs - this advice is based on two 120k ones:

- If you find your breathing's getting heavy, you're going too hard; save that for the last 10-15 minutes. You want to stay just under this limit. I try to keep inhaling through my nose, exhaling through my mouth. If I can't breathe through my nose anymore, I'm blowing up, which is fine if I'm close to the finish but not with 10+ km to go.

- You'll probably like the aerobars. I didn't have them, and I hurt. I have ridden with them on another bike since. They help me get in a zone and focus on my pedal stroke - you sort of isolate your legs from the rest of your body. That, to me, made even more of a difference than the wind resistance benefits.

- Rather than focusing on one leg or the other, what helped me was focusing on one muscle group at a time. I'd focus on pushing down my thighs from the glutes for a minute, then on scraping my feet from the calves, then on pushing/pulling with my quads, and so on.
