Traffic has been backing up as motorists attempt to get off at Junction 7 for Stevenage and head into Knebworth Park.

The 13.1-mile race is due to start at 9.30am.

Posting on the event page, one runner wrote: “Can’t get there as traffic is ridiculous getting in. A lot of runners like me missing the start. It’s a shambles.”

Another commented they had been stuck at the junction since 8am, and one poster from Stevenage said: “Traffic is horrendous. Hope they delay the start.”
