GRIT 100 2026

The race.

The GRIT 100 Challenge is a month-long virtual endurance event held during November 2026 where participants accumulate 100 standard miles through any combination of running, walking, rucking, hiking, cycling, swimming, rowing, or elliptical exercise. All activity miles are converted to standard miles using official conversion charts. Participants track and submit mileage through their RunSignUp accounts throughout November, with a deadline of 11:59 PM on November 30, 2026. Finishers who complete the full 100 standard miles receive a GRIT 100 Challenge Coin, collectable dog tag, and official finisher certificate. Virtual milestone badges unlock as participants progress toward their goal.
