Sheeeet Ronno - Staying with the pack as we age requires cunning. Out of the wind, a tandem to draft on the flats, mid-pack wheel sucker, identifying your pacemaker for the longer climbs, etc.

The best result is a safe finish, with a smile, in time for a cold beer (or hot coffee), and some comradery.
As to the issues about heart rate, etc - consult a sports related Doc. Bypass the GP.
