If they are at all decent guys, they shouldn't leave you behind. I frequently ride with the fast guys in our group (about half the time the girls & 1 slowpoke all ride together instead, we're all of 6 people so it's the luck of the draw for who can make it). They do ride fast - I usually prefer around 15mph, I'm in no hurry and no need to race so I've no interest in 20. The guys tho - they often do at least 18, and it's tough!
One thing I've managed is to ask 2 favors:
1)we don't start out with a hill - because it takes me forever to recover if I'm not warmed up before that first hill and then we go sprinting along at 18. I'm better-than-average (for my group) at hills otherwise, but that's a bad start.
2) We start out around 15mph for the first 10 mins, then speed up. Again - let me warm up. After that, I'm cool and the pace isn't a problem - but I also may not make it as far as I usually would at 15, so I shave 5 miles or so off my current best ride distance.
Thankfully, they're ok with all that. I also know they will never let me fall too far behind, so there's some peace of mind there.
Hope that helps. Let us know how it goes.![]()
