The Course

The course is 5000m (5K) long. This has been accurately measured by us with a professional measuring wheel. The course is in Black Park Country Park, Slough and run on compacted earth and gravel tracks. 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 Black Park 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.
  • 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 make sure you’re fit enough to run 5k (3.1 miles). Health advice about running can be found at the excellent Runners' Medical Resource website.
  • 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.
  • Runners wishing to run with a dog are welcome, but please keep the dog on a short lead or harness and under control throughout the event. Please also review the parkrun support page article about running with a dog at parkrun events.
  • Runners pushing buggies are also welcome, but please take extreme care of other runners around you. If possible start from the back of the field and try to keep to one side of the main body of runners.
  • While rare, Lyme Disease is present in areas where deer live, and occasionally passed to human’s through infected ticks. See NHS Choices website for more about Lyme Disease, and how to deal with ticks.
  • This is a free training event, so all run and attend at their own risk.

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

Age Grading

All parkrun events use Age Grading to help athletes 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 the Running For Fitness website.

Course Description

The course is one lap on firm, flat and wide tracks of compacted earth and gravel. Fast times can be expected. The start is at the east end of the car park. The route goes north for 630 metres before turning right (signed). Follow this wide track (which swings gradually to the right) ignoring all side turnings for 1.56 Kms. Until the main A412 road is reached at the bottom south east corner of the park. Turn right (signed) and go forward for 550 metres with the main road just outside the park on your left hand side until reaching a crossing of tracks. Turn right again (signed) and continue on this track for 350 metres to a fork of tracks. Take the right fork (signed) and continue for another 750 metres ignoring all side turnings until reaching the next sign. Turn left and go forward for 350 metres to a “T” junction at the heathland area. Here turn left again (signed) and run in 810 metres to the left turn and immediate finish.


  • Parking: Black Park has a car parking charge of £2.50 if the ticket is bought before 9am on Saturday mornings (£3.50 after 9am). If you are going to be a regular parkrunner at Black Park then we would recommend purchasing an annual parking pass for £45.00. Details can be found here:

Getting there on foot

The park is rather out of town and unfortunately most of the roads around the park are country lanes with no pavements. For this reason we find that the majority of our participants prefer to drive or cycle.
