Take on a Tough 10 run in the stunning Pentland Hills Regional Park near Edinburgh.

No obstacles - this is the chance to take on 10k of steep inclines over challenging terrain. If the hills don't take your breath away then the views are sure to.

A mixture of muddy tracks and steep, never-ending hill climbs makes this course one of the toughest out of all the Tough 10 events.

The amazing views and stunning scenery will make the thigh-burn worth it!

Here are some of the key statistics of the course terrain:

  • 60% paths
  • 30% grass 
  • 10% mud

This is just an initial course description as it may change before the event.

By car

Please note there is strictly no parking at the venue - please do not continue to drive down Bonaly Road after the A720, to access the venue.

Signs and stewards will be available to follow on the day. Please car share where possible as parking will be on nearby residential streets, so we ask everyone to be considerate of local residents and not to block driveways or footpaths.  Failure to follow these instructions could jeopardise the future of the Tough 10 event for Cancer Research UK. 

There will be 15-20 minute walk from the closest streets, so please ensure you allow ample time to get from the car park to the event venue.

Drop Off Point

Participants can be dropped off at the junction with Torduff Road.

By Bus

From the centre of Edinburgh, Princes Street, the bus stop you need is on the same side as the Castle. Take a number 10 bus to Bonaly shop. It is then a 10-minute walk to the start.

The race will start at 11am. 

Please arrive 30 minutes before the start. You will need your running number that will be sent to you in the post prior to your event.

Before the race starts there will be a short warm up and safety briefing.

This route covers a mix of marked paths, grass and some muddy and boggy areas. We advise you wear trail or fell running shoes if you have them to give you more grip on the hills and muddy areas.

The weather in the Pentland Hills can be very changeable and can be cold and windy on the top of the hills. Please bring spare layers and dress appropriately for the conditions.


The race will be chip timed using ResultsBase.

The timing chip is a blue loop that attaches to one of your trainers and will be sent out to all entrants before the event. 

 Here are some instructions on how to attach it on the day.
