Two of the later obstacles in the Spartan Race involved water. The first was crossing a small river. It wasn’t too deep but the cold water on tired leg muscles was not nice. The banks were also getting very muddy and slippery given the number of contestants that had been before. Then there was a second water crossing. This was across and back the river with bank climbs on both sides. The water was also a lot deeper and the bottom of the river was uneven. Here people really struggled and the tiredness was really showing.
