Okay, my results are posted. I didn't run with a watch, so am going with the "official" distance ... not certified.
This was my 1st "mud run" and was a LOT of fun. I started in the second wave. There were 13 waves of about 40 - 50 people spaced 5 minutes apart. The great news was my sister (new to running) was in my wave.
I decided to just enjoy the experience, so didn't race hard. There were 532 runners, with 459 finishers. Each runner put themselves in a category of their own choice: Hard Core Miner (will race it hard), Light Duty Miner (good shape, but not crazy) and Weekend Warrior (goal is just to finish it). I put myself in the "Hard Core Miner" group, of which there were 63 of us. I placed 18th in that group, and 26th overall with the open field. My official pace was clocked at 6:07/km.
Anyway, there were about 14 obstacles (called Mayhem) over this 6.5 km course. Crawling through mud under ropes, over tires and logs, scaling walls with ropes, being sprayed with water along the way, slides ... you get the picture. VERY steep climbs - it was basically up and down the local ski hill, over and over and over again. Very rough in places - ruts and such - so you had to be careful with your footing.
As I said, a lot of fun. Everyone who finished got a miner's hard hat instead of a medal. Cool. My right knee was a little 'off' - likely due to the downhills I did this week - and so I was very careful on the steep and rough downhill portions of the course.
It was a beautiful morning for this, and the hose down at the end felt great!
I'm going to take tomorrow and Monday off from running, and then ride my motorcycle to Grimsby on Tuesday - a 6 hour ride. I'm running a 10 km there that night, and am aiming to PR it. We'll see.
