JEFFERSON — Midcoast Conservancy will host its 10th annual biathlon at Hidden Valley Nature Center in Jefferson on Sunday, February 20.

All ages and skill levels are encouraged to participate. Biathlon is an Olympic sport that combines cross country skiing and target shooting. This year, the race will include a fat bike option as well, where racers ride rather than ski. There will also be a category for snowshoe racers.

Midcoast Conservancy’s event is a twist on the classic, using paintball rifles. All rifles are provided by Midcoast Conservancy, and each racer will receive safety training on how to use the rifle. Races will begin about 9 a.m. and continue into the early afternoon. All day long there will be bonfires and spectators are encouraged. Biathlon fans should consider volunteering if they are not planning to race; the race volunteer crew can always use extra hands!

Race categories are based on self-selected skill levels upon pre-race check in, and there is a special category for youth racers. Gear will be available to rent for any racers needing skis, snowshoes or a bike. Registration fees are $20 for adults, $10 for kids and students. Early registration is encouraged as space is limited and prices go up $5 per participant on Feb. 13. Register at midcoastconservancy.org/events-list/biathlon. Day-of registrations as space allows.
