The Spring Fling Challenge is a seasonal mileage goal designed to help you and your dog get outside consistently — even when the weather can’t quite make up its mind.
Log 150 miles with your dog during the challenge window and earn the official Spring Fling badge. Mud, rain, sunshine, lingering snow — it all counts.
Log your hikes inside Trail Dog Project.
Miles tracked during the Spring Fling date range automatically count toward the challenge.
Hit 150 miles and earn the Spring Fling badge.
No manual tracking. No spreadsheets. Just miles with your dog.
March 1st – May 31st
Only miles logged within these dates count toward this season’s challenge.
A digital Spring Fling badge added to your dog’s profile
Optional commemorative patch and/or sticker
The satisfaction of knowing you showed up consistently for your dog
Whether you hit the goal early or sneak across the finish line at the last minute, it all counts.
Seasonal challenges aren’t about competition. They’re about rhythm.
Spring is unpredictable. Motivation can dip. Life gets busy.
The Spring Fling Challenge exists to give you:
A clear goal
A defined window
A reason to lace up your boots
Your dog doesn’t care how fast you go — just that you go.
Trail dogs who love long miles
Backyard explorers logging daily walks
Teams building endurance together
Anyone who wants a reason to get outside more often
There’s no leaderboard. No pressure. Just you and your dog working toward something together.
Log your miles. Watch them add up.
We’ll handle the rest.
