Followed your link to the JWOC sprint map, but couldn't figure out how to see the competitors' routes. Could you give me a hint?
I didn't exactly look at their full routes, but there is a play button in the bottom left corner and you can watch them run. You can also uncheck everyone by pressing the circle to the left of the space that says "Competitors..." in it where you can type, then select one specific runner by pressing their circle. If you press someone farther down the line you'll have to drag the thing at the bottom of the screen between the arrows right until you see them move, then place it at the beginning of their run. Tell me if you need any clarifying. :)
...and if you click the REAL SYNC text in the top right corner you get them all (or the ones you´ve chosen) to start at the same time...
Thanks, guys! Didn't see that play button in the lower left corner on my own. Got it working now. Very cool!
