I probably wouldn't use this as a baseline for comparison. It took me a bit over 14 minutes to get to the top and the two guys I was riding with got there faster than me, even though they got off and walked for a bit. Happy to say I rode all the way to the top, but it didn't exactly happen in a hurry
Surely the Garmin doesn't pick up GPS sigs underground? Maybe it just draws a straight line between the the entry to the tunnel and the exit.
