Oops... "recumbent" The edit feature won't let me edit the title
My 72 year old dad is a serious recumbent rider. He has back issues that prevent him from riding traditional bikes for any distance but he rides 20-60 miles/day on his recumbent just for exercise. And I have no doubt he could easily do a 200k ride if provoked.
Is there any reason why I can't invite him along on a randonneur event? My folks are always coming out to Texas to see their grand kids. I might tell him to bring his bike along next time to do a long ride together.
