Online Entry is here – early bird discount until midnight Monday!

Parking    Parking is at St Peter’s Church Hall, Church Street, Addingham LS29 0QS.

The entrance to the drive up to the church will be flagged off Church Street.

NB1: Only organisers can park in the surfaced car park outside the church hall; competitors must park in the field on your left immediately before the entrance to the church hall parking spaces. Parking officials should be present to direct you. Please park tidily.

NB2: the access off Church Street to the parking is a narrow track which is also the route for bikes from the start and back to the finish. Please go very slowly after turning off the main road. Bikes have priority!

Registration is outside the church hall if fine or inside if wet/cold. Please no mucky boots inside the church hall!!

Open from 0915 to 1030

Toilets and Food    Toilets are inside at the far (E) end of the church hall. We are providing hot drinks and biscuit/cake in the church hall when you have finished in return for a donation to charity. There may also be some savoury snacks. No charge but a donation to Yorkshire Cancer Research appreciated.

MapRun   – the event is entirely MapRun based. FAQ here Don’t forget to download the event in advance (folder is UK: North Yorkshire: NYMBO: Summer 2026: Addingham). All the controls have been checked for accuracy but GPS is variable. A Strava backup would be wise, but I’ll listen to pleading.

Start/Finish –Starts from 0930-1030 outside the Church Hall. The time limit is 3 hours with the usual penalties. There are no pre-assigned start times; first come, first served. You will get control descriptions  at registration.

MapRun will start if you tap ‘go to start’ in the car park. So, when told to start, and not before, tap ‘Go To Start’ on MapRun and it should bleep when the GPS finds you at the start. You will be timed from that point.

The finish is in the same place. You have to record at least one control after the start for the finish to register. After finishing please report back to registration to confirm your finish: outside if dry, in the church hall if cold/wet. I cannot see why anyone should cycle back to the start before they want to finish, but if you do, MapRun will end your run. You can restart if near the start by repeating ‘Go To Start” and it will record it as a separate run. We will make adjustments at the end if anything goes wrong.

Course map – the blank course map is below. The map is 1:40000, adapted from the 50000 OS.This is a large and hilly area. I don’t think anyone will get near a full house of the controls, so choose carefully at the start. The map is marked with the usual 30 controls with points values between 5 and 30.  Map size is almost A3: 350 x 295mm. Control descriptions are on a separate sheet.

Important Safety!

1. Kit: some of the routes cross high and exposed moorland. Come prepared if the weather is poor. We also urge you to wear a bright top and use lights as you are likely to use one or two busy A roads. We will check you have a whistle and bivvy bag or safety foil sheet. Will be on sale at the event if Tim remembers.
2. Some roads and routes are marked out of bounds with red crosses – don’t go there!.
3. The Leeds/Liverpool canal towpath runs across the bottom of the map. Places you can leave the towpath onto adjacent roads and/or across bridges are highlighted with blue circles on the map.
4. You can use the pedestrian bridges across the Wharfe in Addingham and Ilkley, but please dismount. The bridge in Addingham has steep and awkward steps.
5. Take great care on your bike leaving and entering the car parking area; the track is narrow.

You must report to the finish. My phone number is on the map if you’re stuck.

Terrain – It’s hilly. The rideability of the bridleways is shown on the map – see the legend – but these are weather and rider dependent.

Any other updates will be here.

Hope to see you at the event!

Just over 2 weeks until our next event, further details next week!

In the meantime, you can enter online here and get the early bird discount!

You’ll find the results for Saturday’s event here (updated Monday).

There are still a few updates to be made before these are finalised, please get in touch if you spot anything amiss.

Thanks to all the people who came to the Thorp Arch event, the weather was kind and felt like spring (until I rode home when the hailstorm seemed to pace me). The Cafe went down well and Tim, the owner, sends his thanks to us for coming. The portions were generous and I was particularly taken by the “Big Daddy Tea”. 

I enjoyed planning the event, this is an area I ride from home but I’d not ridden all of the bridleways before. It took some investigation with tracks on the OS map not agreeing with tracks on the ground, tracks on the ground not being on the map and fingerposts having yet a third opinion. The weekend before, I even found a new section of cycle lane that wasn’t there previously.

There was a last minute change to checkpoint 26 to move it away from the river edge. Thursday brought biblical rain and rivers were high. I thought it best to keep away from the edge so we didn’t trial the first NYMBOA – A for aquabike. 

Despite the rain, tracks were reported as generally dry and running well. One local, familiar with the area, said this caught them out as they came in with significant time to spare. Other locals tried tracks they’d not been on before and people reported liking the variety.

It was a good turn out with 47 people in total. Great to see a few new faces both the older generation and younger in the GEN category, we think the 6 gen pairs at one event is a record our statistician is currently getting his notebook out to check.

Every checkpoint was visited and not just because Andy Conn cleared up. Most riders concentrated on the south of the map sacrificing the far north. There were a couple of interesting routes taken, nearly a visit to Wetherby services and a few routes beyond the extent of the checkpoints. A couple of riders used the footpath alongside the river to go between 20 and 26. A penalty equal to the points of the checkpoint travelled to have been deducted for using a footpath as this would have provided an advantage over using the legal road route. 

Reported incidents included – one puncture, a broken mapboard and an airborne phone on a descent (recovered safely). Someone kindly picked up a Camelback Podium water bottle at one of the checkpoints and handed it to me at the end. If the owner recognises it from the photo on the nymbo website let me know and I will try to get it back to you.

Congratulations to the leading riders

The event centre is Tim’s Café on Thorp Arch Trading Estate.

There’s ample parking and the café is open from 8am to 2.30pm. The trading estate is quite unusual as an ex-military site, now also home to the British Library. The course is relatively flat with most tracks and bridleways having a surface that will be firm despite the wet weather. May even be dry if spring stays!

The area isn’t as rural a usual but there are a surprising number of, and variety of tracks and bridleways. Claire will be checking the course this weekend.

An old railway line runs through part of the course, this can be busy with runners and dog walkers so a bell would be advisable.

The map straddles the A1. There are crossing points by underpass and cycle paths around roundabouts but please be careful of traffic if your route choice crosses a busy road.

MapRun details and Start/Finish locations will be published next week ahead of the event.

The blank course map is below.

14 March 2026 – Thorpe Arch

Results from Saturday are here, Steve’s report is below along with the control map. Thanks as always to Steve for course planning.

Next event is Saturday 14th March and online entry will be open for that shortly.

I was impressed with everyone’s positive attitude when they finished very wet and muddy after 2 hours in that weather – especially if they had ridden through the flooded road within 5 minutes of starting!! Some riders luckily finished with very clean bikes having made #6 their last control !!
I thoroughly enjoyed planning the course but admittedly I did my first 2 recces in October when the bridleways were nice and dry. Then my final check in November when they were frozen solid. However, I did put out the taped route and checked the 3 controls we had to move last Wednesday so I realised that the soft bridleways were going to be a challenge. Unfortunately, at the last minute, I was asked to avoid the tracks on the west side of the nature reserve which is why they were marked OOB. Thanks for avoiding them but you are welcome to use them casually if you come back to ride there when/if the weather improves.
All of the controls were visited, everyone tried at least one of the wet bridleways and no-one used the out of bound tracks on the west side of Scorton Lakes. However, a few riders need to take a bit more care with their navigation so that we stick to the tracks that we are allowed to ride.
5 riders carried on along the disused railway line after visiting #30 instead of turning right onto the bridleway along the edge of the field. 3 of them realised and turned back but 2 riders carried on so will be deducted the 20 points they score for visiting #20
Too many riders continued SW after visiting #18, most of them turned right at the next junction but 3 continued along the private drive, 2 of them realised and turned round but one rider continued to the road on the way to #22 so will be deducted 25 points. 
A few riders kept right at the track junction SW of #21 and continued along the footpath before turning round and a few riders missed the junction SE of #29 before rectifying their mistake. Please take more care.
Congratulations to the leading riders SM Nuno Cerquira 481 VM Paul Dobson 425 SW Jemima Parker 345 VW Andrea Foster 289
Thanks to Ellerton Lakeside Cafe for an excellent event centre. 
Hope to see you at our next event at Thorpe Arch on March 14th when the weather will hopefully be much better!!

Updated – see this newer post for the course map

Bridleway junction between Gatherley and Uckerby

As Storm Chandra makes its way across the country, Steve’s been out checking the bridleways for our next event at Scorton on Saturday 7th February.

The forecast is cold and wet leading up to the event so the soft sections on the 5 bridleways will be tough – however the junction pictured above does NOT feature on the course!!

You can start with some fine navigation on excellent tracks around the reclaimed gravel pits but please give way to the many walkers and their dogs. Then it’s a variety of quiet country lanes in fairly gentle countryside using 5 mainly dry bridleways but please take great care crossing or using the 3 busy roads on the map. The picture below shows a bridleway that IS on the course!
