the team i ride with is mostly experienced racers and longtime riders... one guy i know who regularily toasts everyone is about 58?, and a little pudgy around the middle.. but he showed up with his wife on a tandom one day and still smoked all the "b"group and kept up with the "a" team. not a recumbent but i was really amazed by the speed on that thing considering the weight of it.
lol when i got tired(i am still a new rider) they let me draft in the "cradle". thankfully i finished the 136kms that day still with enough energy to ride home.
no bents on that team, but plenty riding around the city streets.
