A look at what is known so far about the Toughest Mudder event, and based on that, how you can plan your pacing strategy.
Although it’s mildly unrealistic, assume someone who ran three laps ran every lap the same pace and took as much time as possible to do so. That gives them from 8am-2pm to do two laps and start their third. Their total time would be 9 hours for 30-36 miles of regular Tough Mudder including the hills and obstacles. The obstacles at Toughest will be harder, but my overall conclusion is if you could do three laps on a Saturday Tough Mudder, you’ll be able to do 25+ miles of a Toughest. Yes, that means that there will be lots of contender qualifiers. I think this is by design.
