Sara McGrath of Oak Harbor was the first woman in 2:35:08, eighth overall.
Topher Robinson of Crown Point was the top local finisher, taking 14th place in 2:40:40.
The triathlon expanded last year to include a sprint race, which was made up of a 750-meter swim, a 20-kilometer bike ride and a 5K run.
Leslie Reap of Merrimack won the sprint event in 1:29:22 finish. Peter Smith Jr. of Fort Edward finished second with a time of 1:30:45. More than 220 athletes took part. It also included a team event.
Both races started at the Lake George Land Conservancy beach, adjacent to Hague Beach. Swimmers went south towards Jenkin's Point and returned.
Competitors then mounted their bikes. The 40K course headed to Ticonderoga and up Chilson hill and back, while the 20K course went south on Route 8 up Graphite Mountain to West Hague Road to the New Hague Road back to the beach.
Both runs went south on Route 9N toward Silver Bay and back.
