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.”
