I've coached the Tahoe ride for TNT since about 2001 (this year we're coaching Death Ride instead). Tahoe won't be as hot as it sounds like your training has been - but since it's at altitude you will really have to monitor hydration at that ride.

Here's a thread that recently discussed training for altitude: http://forums.teamestrogen.com/showt...light=altitude

Last weekend, I did DMD and it was mid 90's and just brutally hot on the Hamilton climb - one thing that worked well for me is putting ice in the sports bra. You have to really bring your core body temp down when you are starting to overheat. Keeping your water cool is also going to help so it's good you got those bottles!

Also, think about taking your helmet off and getting your head and hair super wet. (Put your helmet back on of course!) This can really help.

And let your coach know how concerned you are about finishing the ride and ask them to monitor how much you're eating and drinking and see if they think you're getting enough.

Good luck.

Go team!
