Every 3 years myself, @rb58 and @Trickedem do a very similar ride in Kent. The Tri-vets 100 miler for those that are 50+. 4 loops of 25 miles with food breaks between each. It's a wholly enjoyable, sociable pace days ride which continues to amaze me of the ages of some of the riders (80+).That sounds good. I have never ridden a 100 miles , best is 55 so far but who knows?
The past 2 editions/rides I have been the youngest.
You also get a nice badge.
Ive got a few years and rides until I get this many
