Really enjoyable race and my first attempt at this type of event with a time limit rather than a set distance. I love running in the rain and mud so this was perfect for me. The organisation for this lowkey Friday afternoon event was spot on and the aid station buffet was great as well. I highly recommend.

This is one of the most fun runs I have ever been to. The race set up from start to finish was perfect. There were determined fast runners and those just there for fun but they all went with the same attitude. All runners supported each other and the run directors were amazing too. As for the race snacks, I would say it was more of a buffet. Everything from sweets and gels to homemade cakes. I can’t wait to go again next year. Thank you.

Event information

Organiser's description

We’ll be heading back to the lovely Rosliston Forest again in for a stomp around in the mud with our special short format.

The runs will be a little shorter than usual, only 4 hours long on a 4km loop, but you can still expect the full Rasselbock experience on the day! You may attempt to complete as many laps as possible over the full four hours, or you may choose to finish just one, either way, you will be a finisher and receive your bespoke medal* when you tap out.

If you're after the Rasselbock love and care, but everything on a smaller scale with fewer runners around then this has to be the event for you.

Here at Rasselbock we love organizing events that we'd want to take part in ourselves. Be it with unique and different styles of events that haven't been seen before, to simply run and submit events with some massive medals! We organise in-person events around the Midlands with a focus on fun, participation, and have no set distance. The majority of the events looped courses with a 6-hour cut-off window. Complete as many laps as you'd like, although you need only complete one to be classed as a finisher! We are a new small company and every person who signs up feels like part of our little family. We'd love to have you on board. Eric + Jonathan
