Sunrise Ultra Finisher2019

Sunrise Ultra was an amazing event & I feel very lucky to have been able to take part in in. The organisation & communication were second to none and the checkpoints at the event were just brilliant with supportive and friendly volunteers.

About Us

Darkside Running

It is late 2018 and two friends got together for an evenings run and discussed how they thought they would love to put on running events that were a little different. Unbeknown to them, Darkside Running was born.

Twelve months later, with the help of a great team, they ran the inaugural sell-out Sunrise Ultra marathons to rave reviews from competitors.  In 2021, after a years delay due to Covid, we introduced its sister event Sunset ultramarathon and marathon.

Our ethos is to draw upon our own personal experiences of running and racing and put on events that are a little different.  At their heart they need to be simple in concept and with minimal fuss, to enhance the challenge and also reduce the environmental impact.  At the same time we want our events to be accessible and as family friendly as possible, so we always look to offer shorter distances but with the same level of support and service.

For now our races are based in and around Norfolk, a county we both adore and which has so much to offer a trail or ultra runner.
