The Saint Francis Tulsa Tough cycling event has had to delay and cancel some of Sunday's proceedings due to the weather.
The Gran 100-mile event has been canceled, and all other Gran Fondo events have been delayed by two hours, with the planned start time of 9:30 a.m.
The Deuce competition has been canceled.
Double Tough participants must ride the Gran Fondo Medio route to earn a Dough Tough jersey. The kid's races scheduled for 1 p.m. today were canceled along with the Townie ride.
Officials will decide on the times for the criterium races at the scheduled time of the race.
"The decision will be based on assuring the safety of cyclists," officials with Tulsa Tough said.
