Our Mission

To listen to Greta

To bring like-minded runners together to enjoy an environmental theme

As a result of preparing a course, what kind of race organisers are we not to take drastic action on the colossal plastic footprint and carbon dioxide leaching into an environment we train in, love and race in. So it's up to us. We are of the opinion that the idea of a run or a swim in the countryside in the future will be purely imaginary. The air and water will be so contaminated with micro fibres from polyester (in our industry the posh name is technical t-shirt) that it will be only possible by taking a pill to satisfy the craving, or by working out in a sealed box with atmosphere controlled by men in white coats. Change is not happening fast enough and it may actually be too late.

While that gives you an idea of what we're about it doesn't tell you what we're going to do.

Recycling plastic water bottles is old style, so we're not buying them in the first place. We are buying though, plant-based eco cartons, biodegradable banners, compostable cups, bales of straw and hessian as a finish gantry, organic cotton as a start bunting, manila hemp rope as crowd control, cardboard and wood as direction signage, you won't see diesel generators, cars with their engines left idling and plastic cups. You can expect passionate and friendly marshals and definitely no meat

It is well documented that you feel happier doing things outdoors and by surrounding yourself with natural materials. The race adventure is of course staged in a stunning framland setting, so instead of planting dozens of fluorescent plastic sign boards ( aka estate agent boards) we're hand-making and painting them from reclaimed wood (solvent free). That big organisation called England Athletics did not approve of us doing this at our last event, and for this reason will not be invited.

Welcome to the Harpenden Ecorun 10k !



icon Race Information

Tired of the usual mass-produced medals on polyester ribbons? Instead how about a bespoke wooden engraved keyring? From the organisers of the first Harpenden Half Marathon and the original Merchant Taylors' Triathlons, we warmly welcome you to this brand new 10k adventure! We're going to try and create a low key, non-corporate atmosphere but the run will be a tough off-road test for sure. Your race starts and finishes in a field just off Pipers Lane with picturesque views of woodlands standing tall behind endless farmers' fields on the southern side of Harpenden. Your course features a beautiful single lap, across entirely private traffic-free farmland. As the name suggests you can expect eco touches in abundance.  Please do let us know of environmental measures you think would improve this race.  There'll be fresh fruit to finish and a drinks celebration  to look forward to later in the 17th century free house, the Lower Red Lion, Fishpool St, St Albans.
