Riders braved rain, hail and flooded riverbeds in Saturday's 31st El Tour de Tucson presented by Casino del Sol Resort. 

The elements didn't stop Juan Magallanes from winning the 107-mile men's race in a time of 4 hours 13 minutes and 54 seconds. 

The rest of the riders didn't have as smooth a ride. Between 500 and 800 riders were unable to cross Sabino Creek because of flooding. Officials told the riders to find an alternate route or take a 'DNF' -- did not finish -- for the race. 

Wet weather has played havoc with El Tour, the largest participatory sporting event in Southern Arizona. Race officials were expecting between 8,500 and 9,000 riders today.
