I scraped the GPX data from strava using the mapstogpx bookmarklet. I used a program called Adze to crop the gpx files so they only contain the Pemi loop part of anyone's recorded activity, and then offset the timestamps so they all start at the same time. I played back the synchronized activities in Google Earth, and used GE's moviemaking tools to set a path for the camera and record the movie. I made the graphics in Google Drawing and added them as transparent overlays in iMovie. Wilcox's pemi loop is no longer publicly available from Strava, so I used his published splits and interpolated the pace.

@@RobertBlakemore nice work, thanks for sharing

@@RobertBlakemore thought about doing this with other routes? R2R2R, Wonderland Trail, Presi Traverse....

@@aehostetler Yeah I've made a few others for my own amusement, mostly White Mountain or Boston trail focused. R2R2R is a good idea. I don't know anything about the Wonderland trail. Finding the non-FKT fast attempts can be a big pain in the arse if there isn't a segment for the entire route. What would you most want to see?

@@RobertBlakemore very cool. Would love to see the other white mountain ones. The AT (I imagine a bit harder to manage) and the R2R2R would be top of my list to see.
