Loon Ride at Mercer Bike Fest

August 1st, 2026 – Join us for the Second Annual Loon Ride at the Mercer Bike Fest.
ICORE (Iron County Outdoor Recreation Enthusiasts) announces the Second Annual Mercer Bike Fest and Loon Ride. The event supports our fund raising efforts to expand the current Mercer bike trail from Carow Park along Hwy J to WinMan Trails ultimately completing a 26 mile loop of Mercer and Manitowish Waters as part of the Heart of Vilas County trail system.
Join us in our efforts by riding a 7, 24, or 50 mile route starting and ending at Carow Park on the shores of beautiful Grand Portage Lake. When you return to Carow Park stay with us for music, food and raffles. Cool off with a swim in the lake! Registration fee includes moisture wicking ride shirt, beverage and lunch. Kids 10 and under ride FREE* when accompanied by a paid adult and do not need to register online. Kid friendly activities at the park after the ride.

Clarification on E-bikes. Due to some confusion surrounding e-bike classes we have updated our policy. YES, they are allowed.  Please restrict your speed to a maximum speed of 20mph. Please use proper cycling etiquette at all times.

Keep to the right on the trail unless passing someone.
When passing someone, always pass on the left and give a verbal warning like “On your left” so they can move aside safely.
Maintain a safe speed. Don’t ride too fast, especially in areas with heavy foot traffic, sharp
turns, or uneven surfaces.
Use hand signals. If you’re turning or stopping.
Pedestrians have the right of way, so always slow down and be prepared to stop if needed. Be courteous. Alert walkers with a friendly “hello” or “excuse me” when approaching from behind.
Don’t tailgate. Give other riders plenty of space.
If you need to stop, pull over to the right side and allow others to pass safely. Never stop in the middle of the trail.

*Free riders are not eligible for T-shirt, or lunch
