Of the routes I tested, C was the fastest. I ran it in 6:29.
B was slower, but not much slower. I ran it in 6:34.
A was much slower. I ran it in 8:05.
Before I ran the test, I expected C to be fastest, but I thought B would be more like 20-30 seconds slower. I expected A to be more like a minute slower. I didn't do a very good job estimating the time differences.
By the way, in a race I would have run a different route. I'd have gone straighter - following the C route in the beginning and then going straight toward the control (rather than running the trail) for the last couple of hundred meters to the control.
