2021 Viper trail half marathon.

18 Sep 2021

Organiser's Description

This event is back for 2021!

See event info on Facebook or distance selected.

THE VIPER HALF MARATHON IS ON 1 DAY IN SEPTEMBER....The shorter grass-snake virtual race is over Christmas and New Year period.

Parking is off of the village green near the pond.  (Public Toilets also located here.)  The 45 bus comes here from Chelmsford and there is also a great bicycle route that brings you through the parks to the location too.

The start and finish is now located in the beer garden of the Wheatsheaf public house.  Registration will take place here from 11:00 hours.  Runners can then let our timer know when they are ready to head off.  Deadline to start is 12noon.  Finish cut of is 14:45.

The (almost) half marathon route is narrative and Strava based.  I'll be out early in the morning to assist your navigation by putting out red/white tape and temporary marker paint at key points (which will disappear if it rains!)  There will also be a tail-end charlie with a first aid kit lagging around at the back.

Bottled water will be given out at the start and there will be a water station that you pass twice out on the course.  Please stop and refill your bottles as it maybe a warm day (I have crossed my fingers.)   

There will be food available to purchase at the Wheatsheaf both before and after the run.  Hand in your race number and get a free drink of your choice (i.e. pint of beer, glass of wine or a softdrink....not a whole bottle of gin!)

The Viper pub has closed down, but the event is still alive!  Now half marathon distance at a new start / finsh location over an amended route.  A smaller field to test out it in 2021.

Route narrative is available to download the week before the race via

11:00 registation and then just let us know when you are ready to start off.  Registration is open until 11:55 and the route needs to be finished by 14:45.  (This is late enough for you to also enjoy parkrun and a second breakfast!)

Car-parking and toilets are located off of the the village green, near the pond.

Bottled water available at the start and water station will be passed twice on the course to refill the bottle.  Free drink available at the finish.

(Virtual 8 snake event is on over Christmas.)
