Run or Walk 100 Miles in 30 Days

Consistency beats intensity — and nothing proves that like the 100 miles in 30 days challenge. Whether you’re a seasoned runner or someone just looking to move more, covering 100 miles in a month creates a rhythm of regular training, fresh air, and small wins that add up.

The average: just 3.3 miles a day.

But the discipline? That’s where the magic is.

“100 miles in a month? It’s not about the pace — it’s about showing up every day.”

Why Take on This Challenge?

  • Builds aerobic base and cardiovascular resilience
  • Supports fat loss and recovery when done at low intensity
  • Encourages daily movement and habit formation
  • Improves mental focus and stress reduction through regular outdoor time

Structure Ideas:

  • Option 1: 3.5 miles per day for 29 days, 0.5-mile celebration walk on day 30
  • Option 2: 5 miles, 5x per week + 2 rest days
  • Option 3: 7-mile long run/walk on weekends + 2 miles daily

Mix it up: treadmill, outdoor, hills, trail, even walking commutes count.

Tracking Tools:

  • Use Strava, Garmin, or Apple Fitness+ to log daily miles
  • Create a Google Sheet tracker (like our RB100 Tracker)
