As someone also in the 55+ age group and a member with the club ~10 years, I also was hesitant to participate in club activities initially. I joined the club for the discounts which more than covered my membership cost. Everyone was younger and faster. I was passed so many times on River Rd, there was no way I was joining the Saturday ride. But I kept running into DC Tri folks at the races who were very friendly and encouraging. So I made an effort to get involved. Evening activities were a challenge due to family issues so I volunteered with the training programs. I learned that age is a non-issue and you can always find someone at your pace. I am now a regular on the Saturday rides who happily let the fast folks drop me like a rock and I ride with folks at my speed. And the friendships I have made are priceless!
