Skegness Tri Club members were out in force for the Nottingham Outlaw 70.3-mile race.
A total of 22 members were among the 1,500 entries taking on the half ironman distance.
The event included a 1.9k swim in Holme Pierrpont Lake, a 56-mile cycle route through the villages of Radcliffe, Lowdham, Oxton and Southwell and a 13.1-mile run to finish.
Some competitors took part as relay teams.
The finish line is a fantastic sight, 200m of red carpet, music playing and friends and family cheering and celebrating.

Julie Hawkesford finished the bike section for her team despite coming off the bike during the race and David Freeman completed his first 70.3-mile triathlon.
