Tough Mudder X at Three Locations in 2018
Tough Mudder produced the first Tough Mudder X a shortened course with function fitness added into the mix in 2017. Instantly, due to the special on CBS and the fast and furious format, became a hit among the OCR Community. After the event, Tough Mudder announced pre-registration for several events in 2018 but recently some of those pre-registrations have been refunded.
