A sprint triathlon will be held from Canaan to Skowhegan on Sept. 15. The race will begin with a 500-meter swim in Lake George, followed by a 15-mile bicycling stage and concluding with a 3.5-mile run. For registration info and fees, call Kelly Coughlin at 474-2224 or email kcoughlin@rfgh.net. Information can also be found on the Facebook events page: Lake George/Somerset Sports & Fitness Sprint Triathlon.

The Seaman’s Church Institute Mountain Challenge will be held Sept. 19-22 at Sugarloaf and Sunday River Ski Resorts. This race features three-person teams that travel and finish together, self-sufficiently for both days on the mountain race courses. Participants brave rugged trails — 25 miles and 10,000-plus feet of ascent across the two days — and irregular weather patterns in northern New England. The funds raised by the team sponsors strengthen SCI’s valuable support services to mariners. For more information, please visit scimountainchallenge.com/SCI/.
