Here's a replay of the 24 Hours in the Old Pueblo ride from 2010, using TopoFusion technology to animate the bike ride's results based on lap times and GPS data recorded during the race.
The Kona 24 Hours in the Old Pueblo cycling event is an overnight mountain bike race that begins at noon Saturday and ends at noon Sunday (Feb. 19-20, 2011) at Willow Springs Ranch north of Tucson.
The 12th annual race includes 1,850 cyclists who compete for prizes as solo riders or on teams.
Each rider tackles a 16.1-mile loop at least once. The group or rider that completes the most laps within the 24-hour period wins.
Cyclists and support teams set up a tent city at the Ranch and live there for the weekend.
