The ICI/PRO 28 Day Challenge started 8 minutes ago!
I'm really stoked to see the results from each challenge as they filter in.
- Who'll be all over this? Drop out - or never start?
- What crazy stories will we read?
- Who's going to win?
Challenge #1 is the longest and for some, will be the most difficult.
There's still time to join the others who've committed to the ICI/PRO 28 Day Challenge.
