Challenged athletes who run with prosthetic legs and swim despite paralysis will compete alongside able-bodied athletes in the 16th annual San Diego Triathlon Challenge on Sunday, Oct. 25 at La Jolla Cove. The competitors will swim 1.2 miles, bike 56 miles and run 13.1 miles from the cove to Torrey Pines State Park.

People can also chose to sign up for the 41/2 hour spin-a-thon or 5K walk that also take place on Oct. 25. Children and families are invited to enjoy the fun zone festivities.
