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

Black Park parkrun is a fun, free event organised by volunteers for the benefit of everyone. We wish to make the event as safe as possible, so participants, 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.
  • 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 one dog by your side, within reach at all times, on a short, handheld, non-extendable lead. Please also see this Support Site entry for further details about parkrunning with dogs.
  • Runners pushing buggies are welcome, but please take care of others around you and do your best to start at an appropriate place in the field for your pace.

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 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

The course is one lap on firm, flat and wide tracks of compacted earth and gravel. Fast times can be expected. The start is approximately 100m along the track at the east end of the car park. All course turns are marked with direction arrows - if there is no sign you should always stay on the path you are on.

The route goes north for 630m before turning right (signed). Follow this wide track (which swings gradually to the right) ignoring all side turnings for 1560m until the main A412 road is reached at the bottom south east corner of the park. Turn right (signed) and go forward with the main road just outside the park on your left hand side for 550m until reaching a crossing of tracks. Turn right again (signed) and continue on this track for 350m to a fork of tracks. Take the right fork (signed) and continue for another 750m ignoring all side turnings until reaching the next sign. Turn left and continue for 350m to a "T" junction at the heathland area. Here turn left again (signed) and run 400m to the next crossroads. Turn left (signed), then in 250m turn right (signed) for a straight 160m to the finish line.


Parking: Parking:Black Park has a 2 hour car parking charge of £2.70 if the ticket is purchased before 9am (£3.70 after 9am). If you are staying beyond 2 hours please purchase an appropriate ticket on arrival. The ticket machines will take cash or contactless payment cards, and require entry of the last 3 digits of your vehicle registration.

If you are going to be a regular parkrunner at Black Park then we would recommend purchasing an annual parking pass for £50.00. This gives year round parking at Black Park, and also at Langley Park and Denham Country Park.

Full parking details can be found on the Buckinghamshire County Council website.

Please do not park in Black Park Road as the local farmers require constant access for large items of farm machinery. Blocking their access puts our South Bucks event licence at risk.

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.

Getting there by road

Black Park is clearly signposted from the A412 between Slough and Iver Heath. It is approximately 4 miles from M40 Junction 1, 5 miles from M4 Junction 5.
