WESTBROOK – The all-female sister event to Tough Mudder – dubbed “Mudderella” – is likely to bring thousands of participants to Westbrook on Saturday, the same day some 300 bicyclists are due in the city for the start of BikeMaine.

Last Friday, Mudderella was hastily relocated from Massachusetts to Westbrook.

Tough Mudder took over Sunset Ridge Golf Links in Westbrook last weekend, and the golf course off Cumberland Street will play host to Mudderella, as well.

Bill Baker, Westbrook’s assistant city administrator for business and community relations, said Friday that Mudderella has some 11,000 participants registered for the one-day event, which is more than last weekend’s two-day total of some 9,000 for Tough Mudder.

Mudderella has now been rescheduled three times, first from Kimball Farm in Haverhill, Mass., to the nearby Amesbury Sports Park in Amesbury, Mass., and now to Westbrook.

Baker said that upon hearing that event organizers were having difficulty with their venue, he reached out to offer Sunset Ridge as an alternative.

In a press release Friday, Mudderella officials said the owners of Amesbury Sports Park lost the rights to their property due to pending legal problems, and the officials “were not informed of this possibility.”

“We want you to know how crushed and disappointed we are to make changes of this scale so close to the event. But we are committed to providing the life-changing experience you deserve,” the release said.

Sunset Ridge Golf Links owner Allen Hayman said Tuesday that his team is “extremely excited and pleased to be able to have another Tough Mudder event. They were great to work with on the last event, and my staff is extremely excited to work with them again this week.”

Due to the sudden change in venues, Mudderella officials have offered participants free parking, as well as free transfers to future Mudderella events if registered participants are “unable or unwilling to travel to Westbrook.” No full refunds are offered.

The 11,000 participants may dwindle, however. Following the announcement Friday, many people posted frustrated comments on the event’s Facebook page, requesting full refunds in response to the venue change. Many said the change gives too short notice and increases travel times.

Over the weekend, a Facebook page, “Mudderella Boston: We Want A Refund,” was created, and already has close to 1,000 “likes.”

Registration for the event costs anywhere from $59-$140, depending on when participants sign up.

Baker said the Tough Mudder course, which was in the process of being broken down this week, has been conceptually redesigned, but is also shorter.

Mudderella events are described as muddy, 5- to 7-mile obstacle courses that are non-competitive and designed by women. Whereas Tough Mudder raises funds for the Wounded Warrior project, a veteran’s support organization, Mudderella fundraises primarily for Futures Without Violence, a domestic violence prevention nonprofit.

Hayman said that he met with Mudderella organizers, who also organize Tough Mudder, Monday to finalize last-minute objectives. Other than a shorter course, Hayman said, there is more emphasis on relaxation and revitalization following the event, with yoga and massage stations set up at the end of the course.

Baker said that due to the anticipated number of contestants, Scarborough Downs will also be used as a parking location, in addition to Idexx Laboratories in Westbrook and the Maine Correctional Center field in Windham, both used for the Tough Mudder.

Hayman said Tuesday that Sunset Ridge has reached out to local restaurants and food trucks “to bring more Westbrook businesses into Mudder Village. These businesses will bring more high-end food service to the event, which should fit well with the Mudderella theme,” he said.
