First, let me say that it's not anything personal with the group I ride with, they're all great guys and some are close friends.
Here's the story: Last May a local group invited me to start riding with them. I got dropped two of the first three rides. Now it's to the point where if I'm not doing 90% of the work, I'm not breaking a sweat. Today, for example, the group rode 80 miles, I rode just over 103. I pulled nearly all 80 miles, literally. The normal sprint places we have, nobody sprinted. Those guys were more gassed than I was and I was going significantly slower than normal due to a stiff headwind. Today's average speed was 18.3, I'm usually 2 mph or so faster riding alone on those same routes. Further evidence is that my avg HR for the ride today was just 123.
The biggest issue with finding a new group is that it would involve two hours of driving total. That said, is it time?
