What is the Walk 100 Miles Challenge?

 

The challenge is to walk 100 miles throughout the month of October, and you can complete the 100 miles in any way you choose. Walking, rolling, running – whatever works for you.

You can choose how to split your miles in the month. Whether you complete over 3 miles every day or longer distances on weekends, the challenge is yours to personalise.
