So you're going to your outdoor group training, and the park is pitch-black except for the pavilion in the middle where your group has set up. You're running a bit late, and in a hurry to get over to the pavilion and join in. Do you:
1. take 30 seconds more and follow the dim path through the low chain fence (posts then one line of chain link holding posts together, about 1.5 feet off the ground)
2. run merrily at the fence and try to jump over, because you're getting fit! and it's a low fence! and it'll warm you up!
So, I chose option 2. BAD move. One foot caught on the chain, the other foot slid on the gravel below, the first foot jerked violently off the chain and my momentum carried me over, meaning that my entire weight landed on the back of my leg, on the chain.
If I can work out how, I'll post the photo of the bruises!
