A good place to find data on races is Motionbased.com ... if you do a search for "Hilltowns" you will get a bunch of ride data. Then...based on the search results...what I do is identify a rider who seems most like me ....based on other rides or other information I can glean.

Here's the data on Tour of The Hilltowns...

That first hill is max 20% gradient....and 5 miles in length....which is nasty. The second climb is 10 miles in length. For that guy's ride...it is basically zone 4 climbing, staying out of zone 5...so for me I would pushing up to 170 bpm. But....no sense monitoring my heart rate during the race...it is just all out on that first climb and whatever happens, happens...likely I will get split off at some point but will hopefully be in a group to paceline with...then just go all out again on the second climb. So not a lot of need to pace myself...it's just all out.

I am going to do this race. Hills aren't good for me either...but there is a pure cat 5 category (no 4s) ...so that is a bonus for me. Plus....this is 2 weeks after the New England Classic (7 days, 5 states, 550 miles) ...so assuming I am not burned out I should have decent fitness.
