Please do not attend parkrun if you display any COVID-19 symptoms

The Course

The course is 5000m (5k) long. This has been accurately measured by us with a professional measuring wheel. The course is at Weald Country Park, Brentwood. The course is run on a mixture of gravel paths, woodland trail paths and grass. Some sections of the course may accumulate mud, leaves and puddles after rain. Dependent on availability, marshals will be at key sections of the course, or signs will be in place.

Please remember that the parkrun uses shared paths. For the continued success of the event, please give way to other park users. This won't hurt your time, it won't stop you from getting a PB and it will make sure everyone continues to enjoy the event.

Please, wherever possible walk, jog, cycle or use public transport when attending the event. If you do have to drive, please consider car-sharing to reduce our impact on both the environment and other park users. Please also watch out for other park users when arriving and leaving. Parking may be limited so try to arrive early.

Course Safety

The Brentwood parkrun is a fun, free event organised by volunteers for the benefit of everyone. We wish to make the run as safe as possible, so runners, spectators and helpers are asked to take care about the following:

  • Please be considerate to the park and other park users at all times.
  • Children under the age of eleven must be accompanied (within arm's reach) throughout the run by a parent, guardian or appropriate adult of the parent's choice.
  • Please arrive by foot, by pedal-power or by public transport if you can - your efforts help to reduce our impact on the park and the planet.
  • Please consider volunteering to help occasionally - this event survives only because of your generosity - please visit the volunteer page for more information.
  • Take care near roads and car parks - some vehicles drive very quickly. Please congregate away from the cars and be careful in particular if you have children. If you’re driving to the run, please drive carefully even if you’re late!
  • When running, take care on uneven surfaces - whether on grass or on tarmac. Watch out for cyclists, other runners, pedestrians, children, dogs, wildlife, park animals, vehicles, park maintenance work, falling branches, bollards, posts and other obstacles around the course.
  • Please ensure that you are fit enough to walk, jog, run 5k (3.1 miles) with us.
  • Remember to warm up before the run.
  • If you see a runner with a serious problem, please stop to help them out and get help as soon as possible.
  • If you’re watching, keep clear of runners on the course, and look after any children and dogs you may have with you.
  • It is not permitted to run with a pushchair and a dog at the same time.
  • Lyme Disease is a bacterial infection spread to humans by infected ticks. Consider protecting yourself by wearing repellent when at parkrun events in grassy or wooded areas. See for further details.
  • You are welcome to take part with a dog, but please keep the dog on a short lead or short harness and under control throughout the event. Please also review the parkrun support page article about running with a dog at parkrun events.
  • This course is unsuitable for buggies due to the mixed terrain and exposed tree roots.

We hope these tips help to ensure that Brentwood parkrun is fun and safe for everyone.

Age Grading

All parkrun events use Age Grading to help parkrunners compare results.

Age Grading takes your time and uses the world record time for your sex and age group to produce a score (a percentage). This score allows you to compare your personal performance against other people's performances even though they might be a different age and a different sex to you - the higher the score the better the performance. The scores can also be compared across different race distances - to allow you to, for example, compare a 5km time against a marathon.

For more information, please see our Support page.

Course Map

Course Description

This event takes place in the beautiful Weald Park, a 700 year old, 500 acre country park on the outskirts of Brentwood and close to the A12 and M25.
This is an undulating 1 lap, anti & clockwise figure of 8 trail course with the start and finish areas very close to one another near the main Visitor Centre at the southern end of the park.
The route is clearly marked with wooden posts and way marker arrow discs with the parkrun logo on them allowing the route to be run at all times.

Starting from the area near the Visitor Centre car park, the route takes runners and walkers around the perimeter of the Belvedere Field, down Heartbreak Hill to 1KM and through the area near the lake into the woods and a long (approximately 1KM) ascent up the gravel path in the centre of the park.
Turn left into the woods (Fox and Broom Woods) and head west and turn due south along a hard packed mud trail, passing through 2KM and following the perimeter path until you exit the woods. Take care through the woods on this section as there are a number of exposed tree roots and in winter this section can become wet/muddy underfoot. Once over the wooden bridge, turn sharp right and onto a grass path, skirting Lodge Field until you reach an open five bar gate. Go through this and you have to cross a narrow driveway that leads to a car park and marshal point. Take care at this point and be aware of vehicular movement. Once you have crossed the driveway, a long descent (through 3KM) down a grass path on Nursery Field back towards the Belvedere Lake in front of you. Keep to the perimeter path and along the grass path close to the northern side of the lake and to the far end of that lake.
Cross back through into Belvedere Field and back up Heartbreak Hill. This is 4KM.
At the top of this hill (visitor centre over to your far right), descent towards the Cricket Pitch Car Park area. Turn right near the toilet block and skirting the bottom of the Belvedere Hill to your left and keeping the separate singular trees to your right, head as far as the last tree and then turn right and descend the grass towards the finish chute near the Visitor Centre car park area and at the same point as where the course commenced.
Please note that it is quite common to see numerous forms of wildlife including deer whilst in the park. The paths are all well maintained but please be mindful of overhanging branches, uneven ground, holes (including rabbit/badger/fox holes) or exposed tree routes. In extreme wet weather, some of the grass and mud trails can become waterlogged but still usable. Trail shoes are recommended for this event but in times of dry weather, standard trainers with a suitable grip would be sufficient
