GeishaGirl says:

I signed up for several challenges, but the miles/calories I'm logging (granted, few) won't show up! For example, on the "Hugh Jass Lion Chase" I'm still listed as 0 miles even though I've done (a pathetic) 3. Do I have to enter something specifically on that page? Should the miles I enter just translate? I don't get it.

Dear GeishaGirl,


It takes some time for the miles you run to show up in the challenges. Try again after a few hours. It may not be a problem afterall.

Success

GeishaGirl, the reason is because both of your runs were entered manually.   When a person creates a challenge they have the ability to select whether or not to only allow device runs. For this challenge, only device runs are allowed (Nike+) which means your manually entered runs were excluded.

Just visit:
www.runnerplus.com/challenge/351

you'll notice at the top it says: "Device Limit: Enabled". Now click the (?) icon next to it to reveal:

"This challenge is limited to challengers with non-edited device runs (Nike+, Garmin, etc.) No hand written runs (manually entered) will be accepted."

I hope this makes sense as to why your runs never appeared!
