This spring challenge runs for two months (April 15–June 15) and lets you participate from anywhere in the USA by logging distance through running, walking, biking, swimming, or any activity you choose—with five different mileage goals to pick from (75, 500, 1,000 miles and more). Track your weekly miles on Runsignup, climb the leaderboard, collect Alaskan flower-themed virtual badges, and score great perks like a race shirt, medal, finisher certificate, and virtual bib. Plus, you'll support Alaskan nonprofits with $10 from your entry fee, and you can earn up to $60 in referral bonuses by getting friends to join!
