Six men are marching 3,863 miles across Britain, whilst carrying 25kg to raise funds for military and emergency service charities.

Brainchild of AB James Mazzoni-Dalton, the ‘Yompathon’ team come from all over the UK, representing the Royal Navy, Army and Royal Air Force as well as the Police, Ambulance and Fire services.

The team will be Yomping through Brecon to capture a selfie at Dering Lines gates tomorrow (October 12) at around 10am. On Thursday they will hit Pembrokeshire (Cawdor Barracks) at around 10:50pm and then head off towards Shropshire for the next leg.

The Yompers’ march will take just over six weeks and cover England, Wales and Scotland. The team will move continually, in relay fashion, covering an average of 97 miles per 24 hour period, stopping only at the guardrooms of military and naval bases along the way.

AB James Mazzoni-Dalton said: “I came up with the idea of the Yompathon because I feel so strongly about wanting to help both former and serving members of the Armed Forces and Emergency Services suffering from mental health challenges.

“The charities I’ve chosen to support are close to my heart: I have been in the British Armed Forces since 1998 and I’m currently serving with the Royal Navy as a Medical Assistant in the Submarine Service.”

Carrying a heavy backpack whilst marching ever onwards is emblematic of the fight with mental health issues that many people have. The team are all intent on making it to the finish line in good health and cheer.

Anthony Hornibrook, Yompathon support driver, said: “Watching those Yompers put one foot in front of the other in the cold wind and rain and still having the will power to carry on is amazing! I am so proud to be here.”

Carl Coleman, Yomper, said: “My toenail has gone blue. It wasn’t that colour when I started.”

The team will need to consume around 7500 calories per day to keep them healthy and all of them recognise that a few toenails will go by the wayside. It sounds like Carl’s could be the first to fall!

If you want to be a superfan, you can Yomp with the team to raise a little money for charity - there is a sponsorship form on their website.

Or if you just want to cheer them on and catch a selfie with the lads, you can also see their location live on their website (Yompathon.com) and track them down to their next Guardroom pit stop.
