The news you’re waiting to plan your calendar around is right here.

We have been working away behind the scenes with some trusted Mudstacle League competitors from across the board, and are both proud and delighted to bring you the NEW UK OCR League.

What’s new?

The first change:

We are running ONE season, all year. No more worrying about dropping places in the Winter league because you don’t fancy the cold. Our season starts with old favourite Brutal on the 23rd February and culminates in the excitement of the Nuclear Challenge Cup on November 2nd.

The second change:

LOOK AT ALL THESE NEW RACES. We have been scouring listings all over the UK, inviting discussion from race directors from as many corners as we can poke our noses in to. These are the races that have confirmed entry and gotten on board. Remember, races get a say in whether they are involved or not, so if you don’t spot your favourite chip timed race, do let us know, but please be aware that they may have opted out for whatever reason.

The third change:

After consulting with some highly respected OCR runners across different teams, we have made the bonus point system a little simpler. We may have a race team, but Mudstacle is a truly independent community hub with members from many teams and locations. We take fairness seriously.

The fourth change:

Your top 5 scoring races in the season will count towards your final score. For teams, the top 15 results of your members will make up your score.

What’s staying the same?

The quality

Race quality is still something we’re keeping a close eye on. Races have to be chip timed and well adjudicated to stay on board, and we’re sure our League member races are going to put on a season to be proud of.

The qualification

We’re still an OCRWC qualifier.

The top 5 racers qualify for pro registration and to qualify for age group, you need to make the top ten of your category.

The registration

If you’re a full Mudstacle member, you’re automatically entered into the League. You can also opt out of our insurance and discounts etc. and just be a League only member. Please make sure you register for Mudstacle with the same name you use to enter races, else things get a little complicated!

Who is involved?

See below for the current list of races on board. We will be trying to add more in as race directors confirm, and we will be relaunching our Mudstacle League pages very soon. So since it’s payday… go wild.
