The course is 5000m (5K) long. This has been accurately measured by us with a professional measuring wheel. The course is in Roundshaw Downs off Purley Way Croydon the site of the original London Airport.  The course is round a chalk downland nature reserve on reasonably wide well defined grassy paths with a short section through woodland.  The grass might be slippery when wet and the woodland section could be muddy a times. Dependent on availability, marshals will be at key sections of the course, or temporary signs 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.  There is plenty of parking space on the neighboring trading estate.

There are limited toilet facilities but no changing facilities, (unless you are a member), at the Dragons Gym next to the War Memorial. The bar at the Gym will be open for refreshments after the event.

The Rounshaw Downs 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 vist 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, deer, dogs, vehicles, park maintenance work, falling branches, bollards, posts and other obstacles around the course.
• Runners with dogs are welcome, but please keep dogs on a short lead and under control throughout the event.
• 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.
• Please make sure you’re fit enough to run 5k (3.1 miles) – if you’re in any doubt, please consult your doctor.
• 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.
• This is a free training event, so all run and attend at their own risk.

We hope these tips help to ensure that Rounshaw Downsparkrun is fun and safe for everyone.

All parkruns 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.
