Maria Parker, mother of 2, recently set a new record for miles traveled in 12 hours. She stopped before the 12 hours were up, and covered 241.01 miles. As noted on the Cruzbike site, “She not only set the recumbent 12-hour course record for women, but she went farther than any previous female road biker had ever done in this race. She also went farther than any woman on any recumbent bike at any UMCA non-drafting 12-hour event. At Bike Sebring in Florida, which appears to be the place where 12-hour records are set for recumbent male riders, the 12-hour record for a recumbent woman is 137 miles.”

The men’s record is 241.5 miles in 12 hours.
Commendable feat. Also, some of these records may interest you. See : http://cozybeehive.blogspot.com/2009/11/10-fantastic-world-records-with.html
Surely worth noting that as far cack as 1967 Beryl Burton set the woman’s (and men’s) 12 hour record on a conventional bike at 277miles……..and a recumbent offers lots of potential advantages (aerodynamics for one) suggesting that the bar should be set higher for this form of road bike.
