Well I went to a local club's group ride yesterday. First real group ride since I started cycling in August of last year. I THOUGHT this was the beginner's ride, but I was sadly mistaken. I hung in for 6 or 7 solid miles of medium and then fast paced riding, then fell out. I didn't feel too bad as 12 miles in I saw that only 6 or so of the original 22 riders were still in the main pack. Others had fallen back as well and I was able to catch up to the back end of the group on the return (tailwind). Overall, the hardest peddling I've ever had to do and a great work out. I basically got smoked and dropped by several 40-60 year olds; I'm 30 (bravo to those guys and gals).
Found out the beginner's ride (no-drop) is on Mondays so I'll probably hit that one up next week. The good news was no flats, no crashes, and I was really worried about how well I'd be able to close gaps and keep on someone's wheel at 20+mph but it actually wasn't that hard. Oh, and I was easily 75lbs heavier than anyone there, so more weight loss will obviously help.
