Ironman officials cancel swim portion of Tennessee triathlon

CHATTANOOGA, Tenn. (AP) — Officials with an Ironman triathalon event in Tennessee have canceled the swim portion of the race after heavy rains made it unsafe.

The Chattanooga Times Free-Press reports race organizers made the decision after testing for E. coli bacteria were more than 20 times higher than safe levels for swimming.

The event features a 2.4 mile (3.8 kilometer) swim, a 112 mile (180.2 kilometer) bike ride and a 26.2 mile (42.2 kilometer) run. The bike and run portions of the race will still be held, and race organizers still consider it an official event.

The race begins Sunday at 7:30 a.m. EDT. It will be broadcast live on Facebook.
