Wye Valley Tunnel Run (Marathon, Half, 10km, Colourburst)

Sun 20th July 2025

A group of runners, wearing various colored shirts and numbers, are participating in a race passing under a bridge with stone and metal supports. The background features lush green trees suggesting a forested area. The ground appears to be a dirt path.

Dimly lit tunnel with rough, textured stone walls. Small lights are mounted intermittently along the left side, casting shadows on the uneven surface. The floor appears to be a gravel pathway extending into darkness. The atmosphere is eerie and serene.

A dimly lit, paved tunnel with stone walls extending into the distance. Small lights run along one side, casting an orange glow. A small light is visible at the end of the tunnel, highlighting its length. A sign on the left shows the number 44 and an arrow.

A stone tunnel with an arched entrance, partially covered by foliage and surrounded by lush greenery. The path leading into the tunnel is unpaved and well-trodden, and the inside of the tunnel appears dark due to shadows.

A vintage signal box stands elevated with a wooden and brick structure. A staircase leads to the entrance, with “Tintern Old Station” displayed on a sign. Surrounded by greenery, with trees in the background, the scene is tranquil and bathed in soft daylight.

A scenic view of a lush green valley with trees and shrubs in the foreground. In the middle distance, there's a historic abbey surrounded by more greenery and a few scattered buildings. Forested hills rise in the background under a partly cloudy sky.

A group of seven people, including adults and children, stand outdoors on a sunny day, smiling and wearing white shirts covered in colorful powder. Green grass and houses are visible in the background, and each person has a race bib with "Color Run" on it.

Really enjoyed this 10km race. Well organised. Lovely route, and especially enjoyed running through the tunnel!

Very well marshalled and a very friendly event. Thank you to the organisers. Parking was in one of two schools - I had a later wave and had no issues. I was expecting this to be a 'flat' run on paving/roads but in reality in is rather hilly, albeit not sharp inclines and on non paved terrain. The tunnel was quite busy at times, dark which made seeing where you were treading very difficult.

I think the organisers need to update the description of this race, it was not "very flat" but instead featured two sets of quite steep steps. The path was very muddy in places and as others have said it is more of a trail run, which was fun just not quite what I was expecting! Some lovely scenery, the trees provided nice shade from the sun and the tunnel was definitely a highlight. The start was delayed which caused some confusion but overall the organisation was pretty good for the price.

Not 'very flat' as advertised. Also, the wave system with the different races wasn't great as there ended up being a lot of traffic on the course. The checking in 'admin' was well organised however.

Great organisation and people, BUT HELL OF A HILL at half way that they don’t warn you about!! Walking up steps/boulders and over the top to the midway point/water station! I pitied the marathon runners facing that for a second time! Once was enough and added 3-5mins to my time! Also little signal so don’t rely on your Garmin!!

The Wye Valley Tunnel Half marathon was a beautiful, well organised race. The route was varied and interesting, with beautiful views over the Wye Valley and 2k in the tunnel. However, the route was a lot more hilly than advertised, with several steep steps and long gruelling hills. The route can also be muddy with small bridges and gates to go through, making it more of a trail run. If I was expecting this, it would have been fine, however the description calls it 'very flat', which it is not, so we struggled a bit! I would definitely recommend this run if you were looking for a good trail half marathon, but it is not a course for a PB. We still really enjoyed the day and it was a great sense of achievement, thank you!

We did the colour burst 2k. Everyone was very friendly and there was a good atmosphere. It would be nice, for next time, if the route could be a little more interesting instead of just running around a field.
