The Sprint is now available on BAOC's RouteGadget. Visit
http://baoc.org/wiki/RouteGadget for introduction or go directly to
http://baoc.org/gadget/cgi/reitti.cgi to draw your route.
Since there was no e-punch, I used the 'No Results' mode where competitors need to enter their name, total time, and any splits that they might have taken.
So, you can draw your route even if you didn't take any splits, just enter your name and total time. If you took splits but missed some, enter the ones you have and RouteGadget will average out any of the missing ones. Of course, more splits you have, the more accurate the animation will be.
Note that RouteGadget requires CUMULATIVE splits. Both splits and total time need to be in mmmss format. For example, 0:57 is entered as 57, 5min43s as 543, and 1hr12min32s as 7232. That's easy.
