I just saw this challenge on another blog. I am doing it! It is to run/walk/exercise 100 miles in 3 months. It started April 1st so I am a bit behind.
It means going on average 8 miles a week. If you don't run/walk, every 15 minutes of exercise counts as a mile.
I need some motivation as my exercise has waned a bit recently. I am excited to do this and am wondering if anyone wants to join me?
