About Us

Most people think Essex is flat. We can assure you that this is not the case!

Adventure Race Essex was formed in 2010 by farmer James Parrish and his fitness trainer Tracey Alexandrou. The Unique location of the Secret Nuclear Bunker,Kelvedon Hatch, Essex and the lack of venues in the South East made this collaboration ideal.The privately owned site hosts other outdoor activities including Rope Runners,Paintball and much more.

Adventure Racing is the fastest growing sport in the country !

Tracey is an established Personal trainer in the area and has over 20 years of experience competing in events like the London Marathon, Duathlons and Adventure Races. She took part in ‘SAS: Are you Tough Enough Borneo Jungle’ has trekked to both Mt Kilimanjaro and Everest Base Camp. Her passion for running and fitness training makes the Lactic Races TOUGH and CHALLANGING but appeal to everyone.

Lactic Rush and Lactic Fallout are both Cross Country Adventure obstacle races.They proved to be very popular with feedback like “That’s the muddiest, wettest,most enjoyable race I’ve ever done” and described as `Epic`.So due to the overwhelming demand [from the KIDS!] Mini Rush 7-13yrs and Teen Fallout 13-17yrs have been added.

All the Obstacles are created and built on site to maximise the diverse natural landscape. This allows the team to be versatile and change the races so there is always an elimante of surprise………

In January 2012 Adventure Race Essex launched two additional races to cater for Mountain Bikers. A XC Duathlon in June and XC Mountain Bike Enduro in September, which is being headed up by Damian Williams.

The Nuclear Burn Duathlon includes an Ultra and Sprint distance all set around The Secret Nuclear Bunker. The diverse land offers a wide range of elements from single track, tough up’s and down’s a technical section, water and of course a few long up hills. This will test any rider from novice to pro.

The Nuclear Blast is a Mountain Bike Enduro race set around a similar terrain as the XC Duathlon. The event will be split into 2 & 4 hour races and a 1 hour open “Family” ride for those from 12 years old.

Adventure Race Essex ticks all the boxes for a good days racing by allowing access to some of Essex’s undulating and beautiful countryside. We have good road access, trade stands, refreshments and free parking. Various other activities for all the family are available at the Bunker site.

Groups and corporate bookings are welcome and a discount is offered for more information contact
