This weekend’s Ironman 70.3 wasn’t without sadness; local competitor Sam Land died before he could participate and another person died after trouble with the swimming portion-but the triathlon did go on. 

More than 3,000 athletes from around the world competed Sunday, and countless more came to witness the feat-a 1.2-mile swim, a 56-mile bike ride and a 13.1-mile run. 

Both the men’s and women’s winners praised Chattanooga, the volunteers and the spectators.
