i put the schmeephone to good use yesterday when jg and i went for a hike up to saddle rock. i used a free app called trailguru to map the trail.
the stats are full of surprises. all these years i thought i was doing a 3 mile round trip. turns out to be less than 2! and who would have ever guessed the elevation gain? jg used to think it was at most 500 feet.
i don't know how accurate the information is, with the app being free and all. but i like how it differentiates me and jg: the crawler thinks the trail is twice as long as it really is, while the aggro thinks it's only half as steep.
