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
The route is a 4.28 km long loop of trail running, a mix of gravel path and soft mud. After leaving the HQ you will snake down to the ponds. From here a dogleg out to the muddiest section of the route before looping back round to the HQ.
You'll receive your pre-race briefing via email roughly ten days before the event date that will be packed full of all of the information that you may need to know.
There is ample parking available onsite. As always we encourage people to car share or use public transport as much as possible when coming to our events. Make sure that you post in the Rasselbock Facebook Group if you are able or are looking for someone to car share with.
Rosliston Forest is located between Birmingham and Derby, easily accessible by car and public transport.
It is best to pop over to Google to plot your exact directions to the park as there are multiple different ways to come to it (Forestry Centre, Swadlincote, DE12 8JX).
You’ll be able to pick up your race number at the event when you arrive. The forest will be open from 8am, but you won’t be able to grab your bib until 1:25pm Please allow yourself enough time to grab your number before the race briefing five minutes before the run begins.
We will have a fully stocked aid station at base camp full of all your favorite items, although if you are expecting energy tablets, gels, and supplements, you may need to bring your own as our aid station tends to lean towards the more “enjoyable fuel”. Imagine Fudge, cakes, cookies, and jelly babies along with all the savory alternatives.
You are more than welcome to bring your own food and drink to the aid station. We will have a separate table for these so please make sure that your bottles or items are clearly labeled so that no one takes them by accident!
We do not have any secure baggage areas on site but you are more than welcome to leave your bags at the base camp. Whilst we can’t guarantee that they’ll be safe, there will always be someone from Rasselbock around.
We would recommend trail shoes for this route! Also please make sure that you wear and bring with you adequate layers to keep yourself warm throughout the race and just as importantly, once you finish. Like all of our events going forward, we will be operating a bring your own bottle policy. We will not be supplying plastic cups or drinks receptacles at this event so that we can cut down on waste and do our part to help the environment. You will be required to bring your own water bottle, collapsable cup, or similar to the event. We will still have an array of liquids available for you to top up your bottles with at our well-stocked aid station!
The event will be taking place on and around a working forest that will still be open to the public. Runners will not have the right of way and we will need to be considerate to all the other users of the area, be it walkers, cyclists, dog walkers, and children when passing through any of the “activity areas”

Organiser's description
After much deliberation, we’ve decided that the Rosliston Rumble in the wetter months will now be known as Mudfest! We’ll be heading to the lovely Rosliston Forest again in for a slew of dates next year on 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.
The aim of our events is to organize races as if I was taking part, so you can expect amazing support, the best medals, and a small group of runners that is never any more than 30. Think of it as a small group of friends and family all coming together for an amazing day of running!

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
