When I did tough mudder I was with a group from my gym. Some of us were fitter than the others. There was a group of 3-4 guys running up front and every now and then we would stand and wait for the rest and carry on. After we finished, one of the slower ones was talking about how much harder it must have been for me, since I was going faster the entire time. I pointed out it was probably a lot easier since we were having pauses every now and then and they just had to keep on going. I think at that point they realised they should have ran up front with us.
