24, 12 & 6 hour MTB Endurance race & 4 day off road cycling festival

Sweet Sixteen! Yeah that's how old this event is.


A 4 day off-road cycling festival built around a 12 / 24 hour endurance event. TwentyFour12 is biggest mountain bike endurance event in the UK with 4 days of exciting events for all ages and all the family. The schedule is stacked and includes a trail run, kids racing, enduro and of course the 24hr, 12hr and new for 2022 the 6hr event.


Like all 16 year olds this event is constantly changing and evolving. For 2022 we're introducing a new 6hr Category for those that think 12hr / 24hr is just that little bit too far and too crazy. We've tweaked some of the categories to reflect the number of entries we had in 2021.


We're making the Ultimate USE Enduro bigger than ever. It will become fully chip timed and operate on a "Mash Up" from 4pm until 9pm so riders will be able to ride run and after to perfect their lines. It also means that if you're not lucky enough to be able to take the Friday off work you should be able to come down after work and compete.


Those are the major changes but we'll also be making others based of feedback from the 2021 event.


Twentyfour12 is an endurance Mountain Bike Race around a course of approximately 12km, entirely off road, with a family friendly festival vibe.


Whilst the main part of the event is the 24 / 12hr event we also have so much more happening such as the 10km Trail Run on Thursday evening. On Friday we have an Ultimate USE Enduro MTB event using 6 famed sections within Newnham Park.


The kids skills and thrills training session went down a treat at the 2021 event so that back for 2022 and happens on the Friday afternoon. That's all in preparation for the kids 12 / 24 minute race on the Saturday morning.


The "Hot Lap" event that we held in 2021 has evolved and now becomes the "Short Course" event. 20 riders race against each other over a short lap for just 20 minutes. Super fast and close racing where young and old can compete against each other. We'll also include a eBike version of the short course race *minimum age 14yrs


On top of all that we've got bike demos, more live music than ever before, trade stands, social rides, FREE Camping and much much more.

See the weekend's schedule here (may be subject to change):




Exposure Lights12 Hour Races (Saturday Start)

Solo (18yrs + )

  • Yes that’s right just you and your bike doing as many laps as you can in the time allowed. There are two solo categories under 40 and over 40. Please note minimum age to enter the 12hr race is 16yrs
Pairs (16yrs +)
  • 2 of you means someone to hand over when you’re tired, wet, injured or you just fancy a brew, men, women and mixed pair categories available.
Teams of 4 (16yrs +)
  • 4 of you spread the load, which means strategy and planning or just arriving at transition to find noone there and shouting very loudly until your cries are heard. Also means that not everyone needs amazing lights with plenty of opportunity to recharge both yours and the lights battery.
  • Riding the 12 hour event means you get to finish at midnight sit round the barbie, crack open some beers and heckle the brave souls who are carrying on for the full 24.

Exposure Lights 6hr Races (Saturday Start)

The event will start at 11am on Saturday as part of the main race.

  • Solo (16yrs + ) Yes that's right, just you and your bike doing as many laps as you can in the time allowed. Male, Female Categories. Category is limited to 100 riders.
  • Pairs (14yrs +) 2 of you means you have someone to hand over to when you're tired, wet, injured or you just fancy a brew, men, women and mixed pair categories available.

Exposure Lights 24 Hour Races (Saturday Start)

Solo (18yrs +)

  • Keith Bontrager says you don't race for 24 hours solo, you just exist. Well that may be true but there are some mad people out there who do it regularly and can perform well without any sleep. These people usually have a dedicated team of helpers keeping them fed, watered and working (often affectionately known as pit bitches). These people should be marvelled at and celebrated (riders and bitches). This category is limited to 100 riders. For 2021 Exposure TwentyFour 12 will host the National 24hr Solo Championships (TBC).

Pairs (18Yrs +)
  • Same as 12 hour pairs...except twice as long. In many riders opinion 24 hour pairs is harder than 24 hour solo for deep psychological reasons... try it and you'll agree. This category also sells out...we have no idea why it is popular... prizes will be awarded for top 3 in each category.

Open Teams (18Yrs +)
  • 4 riders in a relay format, you can choose who goes when and whether they ride 1, 2 or 3 laps at a time (this means less changing over and less time wasted in the relay transition), this also means that you just be able to get some sleep but make sure you have a good alarm clock for that 4am changeover. There are male, female, mixed and Veteran categories.

Kids Skills & Thrills Training (2pm, Friday)

The Kids Skills and Thrills training sessions. Qualified coaches will take the kids (in age groups) off for an hour of skills training. With an emphasis on having fun through learning the coaches will work with the kids to develop their bike handling skills. You must pre book this as places are limited.

Kids Racing (Saturday)

On the Saturday morning it's time for the kids to take to the start line for the 12 or 24minute XC race. The U16's and Under 12's will race over a slightly longer more technical course for 24 minutes whilst the U10's and U8's will complete on a slightly shorter course for 12 minutes. The category chosen should be based on the child's age on the day on the day of the event.

  • Sabres - U12's – *9.30am
  • Storms - U10's – *9am
  • Rogues - U8's – *9am
*Times are approx. and will be confirmed nearer the race day.

Ultimate USE Mini Enduro (4-9pm, Friday)

Back in the day Newnham Park was regarded as one of the best XC World Cup courses in the world. What made it special was it's "Gnarly" (yes they used that word back then) downhills which made the venue famous. Sections like "Cottage Return" used to put the fear of god into the best riders in the world. These sections will be more technical than the standard course. We're not taking you down anything super technical and dangerous but they will certainly test the skills. 6 varied stages taking in some of the old favourites and a few new ones that will challenge any rider. The rider with the quickest times overall for all 6 stages is the winner... Simple but loads and loads of Fun! Unlike in previous years we're moving the Enduro to a "Mash Up" format. This means that between the start time and finish time you can ride as many of the stages as you wish over and over again. The event will be chip timed and results will be taken from your fastest run on each section. You'll be able to session the stages over and over again to perfect your lines and improve your time. Categories for this event are:

  • Male and Female - Standard Bike
  • Male and Female - eBike
Prizes will be awarded to the first 3 in each category plus the 1st Vet (40+) in each category. Minimum age is 16yrs

Exposure Lights 10km Trail Run (8.30pm, Thursday)

It's not all about the bike! Lets kick off the weekend with a 10km adventure trail run around the beautiful surroundings of Newnham Park, supported by Hoka One One. Steep climbs and tricky fast downhills... we've set a course that we test any runner whilst at the same time will be one of the most fun runs you've ever done making it suitable for all. This run is different to other runs in that you'll need your lights!! Yes this is an evening run starting at dusk and finishing in the dark!!
Newnham has got so much to offer for a trail running lover. It's got lots of hills (up and down), hard stone tracks, muddy single track sections, water holes... the course we put together includes bits of everything whilst also taking runners off the beaten track.
Don't expect any walls to climb over or barbed wire to go under. No boring grass farmers fields…. This is a "Trail Run" we use one of the best and most beautiful areas in the country filled with fantastic natural trails that make the area such a destination site.
The course / route is a tough one but that doesn’t mean it’s not suitable for everybody. We don’t time cut offs or anything like that. Some runners will choose to blast round whilst others will run / walk the route and just enjoy being outdoor enjoying the experience.

  • Medal and goodie bag for all finishers
  • Under 16's must be accompanied by an adult

Short Course Race (6.30pm, Friday)

Limited number of riders will race against each other for a maximum of 20 minutes over a short course. All ages (14+) can do battle over a short format XC course. Close and fast racing for the full 20 minutes. Riders love it, spectators love it… get yourself signed up as we’ve got limited numbers! Prizes for top 3 Male and Female. Standard MTB's start at 6.30pm, eMTB's from 7.00pm.


General Information

As the name suggests there are multiple races taking place at the same time on the same course. We have 24, 12 & 6 hour races all starting at 11am. The 6hr will finish at 5.00pm, the 12hr at 11pm and the 24hr continues on until 11am Sunday. The venue is perhaps England's finest XC mountain bike site with beautiful scenery, a flat arena/camping area complimented by a course that has been used for five rounds of the Cross Country World Cup in the 1990s. It continues to have a superb reputation for variety and fun riding and is able to withstand some horrible weather and still be rideable.

Which race do I choose?

Well ask a few questions of yourself first:

  1. Have you raced your Mountain Bike off road before?
  2. Do you have people who will be able to keep you and your bike moving?
  3. Do you have high quality lights with a long ‘burn time’ (how long they will last before needed recharging).
  4. Can you perform well with little or no sleep?
  5. What preparation will you do?
  6. Will it freak you out being alone in the dark woods at night?
There are lots of other questions but this event is meant to be endurable and enjoyable so if you have lots of No answers to those questions then you should really be thinking about getting some like minded souls together to form a team or a pair, this will make the weekend more sociable and will aid your ability to prove that you spent the weekend taking part in a 24 hour mountain bike race, challenging yourself and creating memories to tell everybody when you go back to work on the Monday.
