Take a look at the track from today, you didn't have GPS for the first 34 minutes, so you don't get credit for that climb either :)
The distance during that period is the watch's guess from your cadence.
edit: Glen beat me to it.
Also, is that southern part of the valley trail open again yet?
The part between Blagden and Joyce is open, but very muddy and slippery (even more so than the other trails). The part from Joyce up to where Beach Drive crosses the creek is ostensible closed, but they let me run on it two weeks ago - a ranger stopped me, asked me to stay off the road, and was fine with me running the trail.
Em .... muddy and slippery long run on the way back from injury? Been there done that. Good luck!!!!!
