Grit 100

The GRIT 100 Challenge by Gritty Soldier Challenge is a month-long virtual endurance challenge built to test discipline, consistency, and grit. Your mission is simple:

Accumulate 100 standard miles during the month of November 2026.

This challenge is designed to be accessible to all fitness levels and training styles (which eliminates any excuses 😉). Challengers can complete standard miles through multiple activities to include:

• Running
• Walking
• Rucking
• Hiking
• Cycling
• Swimming
• Rowing
• Elliptical

All activity miles will be converted into “standard miles” using the official GRIT 100 conversions (SEE CONVERSION CHART).

Challengers will track and submit their mileage throughout the month, as they complete it, directly through their RunSignUp account. (SEE REPORTING PROCESS)

Virtual milestone badges will be unlocked along the way as Challengers progress toward the 100-mile standard.

This challenge IS NOT about being the fastest.

It’s about showing up when motivation fades, staying consistent when life gets busy, and proving to yourself that you can keep moving forward long after most people quit. It also about breaking into new milestones and proving to yourself you CAN DO IT.

This, is a test of GRIT.

100 miles. 30 days. No excuses.

Join fellow runners on November 1, 2026 for the Grit 100. It's a fantastic Ultra featuring a flat and fast course in Anywhere.
