Format, timing, and fundraising
Runners select a heat by expected 5K pace: a fastest heat, an intermediate heat, and a third open heat. Field sizes are limited for some heats and walkers have a dedicated lane. The race is professionally chip-timed and provides split times for each lap completed. Hand tally counters are available for lap counting, but participants are advised not to rely solely on the timing provider for lap counts. Long-sleeve shirts are available for purchase if ordered by December 22, 2025, with limited quantities on race day. The event is a fundraiser to support radon mitigation in low-income Maine households; 100% of registration fees and participant donations are used for that purpose. The stated fundraising goal for 2026 is $7,500, intended to fund mitigation for up to five homes. The event may be canceled for unsafe travel conditions; cancellation and refund policies apply.
