The Viper 15 mile trail run

28 Aug 2017

A new longer snake titled races have been added to our 2017 calender!  They offer a good workout for those signed up the the Chelmsford Marathon later in the autumn, but are more off road biased. 

TRA permit number: 937.

The venue: Admirals Park is situated in the county town of Chelmsford, Essex.  Those of you who do the local parkrun will know our start/finish location as "The hill!"....others as the venue for the summer beer festival.

Parking: A car park is nearby, but has limited spaces.  There are plenty of further car-parks in town.  Bicycle racking is located at the start finish area too, so ideal for those who live locally and/or triathletes in training.

Registration: Registration is open from 08.20am until 09.20am near the start line / toilet block.

This is where you will collect your race bag that contains your race number, high vis' event tee-shirt and a gel or bar from  Safety pins are available at registration too.  We encourage you to wear the T-shirt during the race. PLEASE NOTE, T-SHIRTS WILL NOT BE AVAILABLE TO ENTRIES AFTER 13/08/2018 & BASEBALL CAPS WILL BE ISSUED AS AN ALTERNATIVE.

TRA club members:  please show us your TRA membership cards to confirm your eligibility for the discount received when you complete the online registration process (£2 fee if you forget it.) 

Race numbers to be worn unfolded on your front so we can record your finish times.


Race Briefing 0920hrs.  VIPER 15 RACE START IS 0930hrs.  GRASS SNAKE 12 START 0950.   Cut off is 1300hrs for both distances.

This is a mainly an off-road run with some sections on the open road, so headphones and similar are banned on safety grounds.

A full narrative for both distances will be available to download from our website from August 2017.  

Follow bright pink and yellow marker paint along with the bright orange tape.  Limited signs on course to minimise the chances of route sabotage!  15 follow pink & yellow on the way out then just the pink from 6.5 miles, 12 mile runners at this point will take a left turn.  15 mile runners will follow the yellow paint from 9.5 miles (a right turn on the return leg). 

Dog runners are allowed, but must be on a short lead at all times.  Deer, rabbits, horses and cattle are a feature of the route!

You will be given a bottle of water at the start.  If you wish to carry it with you, you can exchange it for fresh bottles at the water station.  Big thanks to Essex & Suffolk Water for supplying the water.

No littering on course.  If you can take it out with you, you can bring it back too.  Besides, if you're seen dropping litter you get DQ'd!

You'll pass the water station twice.  Please pause so we can record your number (safety head count). 

You are expected to be self sufficient on the run.  We may have a lead bike and will have a backmarker marshall sweeping the course.  First aid help will be available, but due to the terrain it may take some time to reach you.


At the finish line of the race collect a finishers medal, help yourself to cupped water, then head home to recover!

Unofficial 15 course record:  Gary ROBBINS 2hrs31mins


Awards for top three of males and females. 

Full results will be on our website within 24hrs.
