12th Feb – There have been a few queries from newbies to see example maps from previous events. Here is a link to the 2020 maps to use as an example. 2020 Maps

10th Feb – The fab course has pretty much been set. It has been cold and Chilly in the wind. I’ve bumped up the links to Sunday’s Forecasts as they are changing. Some have been in touch to say that they have not received the email I sent out. I plan to send another one to participants tomorrow. Link to the last one here, excuse the mailmerge jargon.

2nd Feb – We are really looking forward to seeing you in Braithwaite on the 13th Feb. I have been busy sorting the maps to showcase the wonderful Lake District. Participants who have signed up, expect an email in the next day or two.  

4th Jan – We’re looking forward to seeing you all in February. I have now manually entered the 45 participants who were signed up through the Open Adventure System. 

We are excited to announce that Tri-Adventure will continue to deliver the Open5 Series that James at Open Adventure set up over 15 years ago.

The next event is Sunday 13th February 2022 from Braithwaite near Keswick in the Lake District. Expect the same setup as previous Open5 events. A 5-hours period to collect as many points as possible within the time limit, this is done by visiting checkpoints of varying points value. There will be points lost for arriving back late. The event is open to solos and pairs using their navigation skills both on the mountain biking and on the running trails.

The Open5 Concept
You will have 5 hours to visit as many points (controls) as you can. Some can only be collected by mountain bike others by foot.
The event will use the SPORTident system of scoring. SI Cards are available to rent at £2.50 per person or can be purchased on-line from SPORTident.

E-Bikers are welcome as we like to be all-inclusive. You’ll feature in the results as a ‘non-comp E-biker’ and out of the running for any prizes.

New to Open5 events? – Check out more about what to expect here.


If you are more than 5hrs in collecting the controls you will incur penalties at the following rate (Please note these values will be reprinted on the control description card which will be given to you at the event)

1-10 minutes 2 points per minute
11-20 minutes    5 points per minute
21-30 minutes 10 points per minute
31-45 minutes 20 points per minute
46+ minutes lose all points


The cost of the event is £35 per person, this does not include dibber hire. Entries on the day are accepted for an extra £7. Pre-entries will close at midnight on the Thursday before the event.

Transition, Start and Finish
The Start/Finish and Transition for this event will be 2.3 mile away from the HQ and Registration. Across the A66 and down a country road.

Timing Dibbers

Timing dibber hire is not included in the entry fee. These can be hired for the event at a cost of £2.50. Alternatively, buy your own personal SI-Card 8 or 9 from Sportident here.

Each Open5 event has five entry categories; 2 solo categories (Male and Female) and 3 pairs categories (Male, Female and Mixed).

The Event Day Process
Register at the event center any time from 8.00 to 9.30 where you will collect a map preprinted with the location of the controls. If you have entered as a pair you must register together.

Solos start between 9.00 and 9.30 and pairs start between 9.00 and 10.00, electing to run or cycle first. At the start you will be given a list of control descriptions each assigned a value. After 5hrs penalties will be incurred.

We only know that for sure once you have returned to registration and downloaded your timing chip. Please do this before 3.30pm – if you don’t we will most likely delay prize giving and task volunteers to start looking for you. Ideally please do so before heading to your car.

Registration 7:30 to 9:30; Solos start between 9.00 and 9.30 and pairs start between 9.00 and 10.00

Prizes will be awarded to 1st, 2nd and 3rd in each category.

There is parking for everyone at the Braithwaite Hall, some hard standing and the rest will be on the field. Take care turning in to the car park from the A66.

Camping at the hall
The is the option to camp/van cap overnight in the field on the Saturday night. There will be access to the toilets and a shower. The cost will be £12 per person and collected in the morning by cash or card.
