The CW Network and Tough Mudder Inc. will will debut a new multi-platform, six-part series next year about “everyday heroes” attempting a Tough Mudder obstacle run. The docu-series, with title and premiere date TBA, will debut on CW Seed and The CW in 2017.

The series will follow a group of people who join up to run a Tough Mudder, the grueling endurance race that tests teamwork skills, physical abilities and “mental grit.” Shot documentary style, the unscripted drama series will cover the team members’ personal stories as well as the obstacle preparations.

Episodes one through five will debut on CW Seed, The CW’s digital network. The finale will feature the team tackling the course and will be broadcast on The CW Network.

“Tough Mudder is excited to partner with The CW Network as we continue to expand our brand through a concerted content strategy distributed through unique partnerships, live streaming, and social and digital media platforms,” said Will Dean, Founder and CEO of Tough Mudder, Inc.

Flatbush Pictures and Judd Ehrlich, the award-winning documentary team behind We Could Be King, the 2014 Emmy Award winner for Outstanding Sports Documentary, will serve as executive producers of the series, along with Jesse Bull of Tough Mudder. Ehrlich and his team produced the Tough Mudder web series Finish Strong.

In August, CBS Sports and Tough Mudder Inc. announced a multiyear partnership to bring Tough Mudder endurance events to broadcast, cable and digital. That deal includes six events in 2017 across North America and the UK with the option to add more in the second half of the year.
