How it counts
Each log counts as one done.

Length
One year from the day you start
Walk 10,000 steps a day, and count the days you make it. The summit is 300 days: that leaves room for sick days, long flights and the odd day on the sofa.
Log once a day, after your phone or watch passes 10,000. Errands, stairs and pacing through phone calls all count. Put the number in the note if you like.
