Which path should I choose for my training?

You have two distinct ways to play this, and choosing the wrong one will frustrate you. If your goal is habit formation or recovering from an injury, take Path 1 (The 21-Day Movement Challenge). It requires just 1 mile of movement every single day. It’s about the streak, not the speed. If you are in a heavy base-building phase or chasing a high-mileage month, take Path 2 (The Solstice Chaser). This is a pure volume game where you accumulate as many miles as possible for the leaderboard. Don't pick Path 1 if you're trying to hit 80 miles a week; pick Path 2.

What do I actually get for participating?

Since there is no single finish line, the rewards are incremental. You earn physical "milestone" buttons to be picked up at the =PR= Run & Walk shop in Midlothian: a River Sunrise Button after Week 1, a City Sole Button after Week 2, and a Solstice Sundown Button after Week 3. If you want the full kit, you can opt for a $25 finisher shirt that supports a youth running camp. The real "prize" is the community gathering on June 21 (Father's Day) at the shop to collect your gear and celebrate the finish.

How do I track my progress?

The entire challenge is managed via Strava ↗. You don't need to submit spreadsheets; you just need to ensure your runs are logged within the official club. This is the most important logistical step—if you aren't in the club, your miles effectively don't exist for the leaderboard.

Is it going to be too hot to train?

You are running in Virginia in June. Expect humidity that feels like a wet blanket and temperatures that will climb quickly into the 80s (F). If you are doing the "Solstice Chaser" volume challenge, do not attempt your long efforts mid-day. Plan your mileage for the early morning or late evening to avoid heat exhaustion. This is a test of heat management as much as it is a test of mileage.
