Changes

** '''Privacy'''. Can you control who sees what from your workouts? You might be okay with sharing your overall statistics, such as distance and time, but not the GPS track.

** '''Friends/Followers'''. Is the model like Facebook where you are symmetric friends, or more like twitter where you follow others?

** '''Challenges'''. Are there challenges, such as "run 100 miles this month"?

** '''Segments'''. Is there a list of best performances for specific parts of a route? This can be a big motivator for some folks.

** '''Altitude correction'''. GPS is notoriously bad at altitude, and even barometric tends to have problems, so automated altitude correction can be handy.

** '''Footpod'''. Because a footpod can be more accurate than GPS, a running log should honor the use of that data. Having the training log override the footpod pace/distance with recalculated values from GPS degrades this.
