A military-inspired 4-day charity endurance challenge where athletes ruck 25 miles a day across Central Massachusetts and camp out at local breweries to benefit Why Me & Sherry's House.
Official event pageWhat this race demands
This 4-day charity endurance challenge demands continuous daily coverage of 25 miles on foot while carrying a heavy ruck across Central Massachusetts.
Continuous Durability
Covering 25 miles per day across four consecutive days requires exceptional muscular endurance and joint resilience to handle high cumulative impact without breakdown.
Load Carriage
The military-inspired rucking format demands specific conditioning of the shoulders, back, and core to sustain posture and locomotion while weighted.
Multi-Day Recovery
Sleeping at local breweries and returning to the road each morning places a premium on post-walk nutrition, sleep hygiene, and lower-limb recovery protocols.
Given the extended duration of daily walking efforts lasting well beyond 2.5 hours, athletes should aim for a consistent intake of 30 to 60 grams of carbohydrates per hour alongside adequate hydration to sustain energy levels.
