The number of Master’s athletes has dramatically increased over the past two decades. And right up there in popularity are the cyclists including road, off-road (fastest growing) and triathletes. According to USA Cycling’s website, 53% of members are age 35-54 and only 19% are ages 19-34. Looking at cycling versus running clubs is always a good indicator. There are definitely not as many older runners, probably because running can be so destructive on the body over time, so a lot of older athletes (ex-runners) are finding the bike to be the key to continued activity and enjoyment.
