It will be an early start, with registration and a safety briefing at 6:30am before the challenge begins at 7am. Your first summit of the day will be Castle Rock, a volcanic plug on which Edinburgh Castle sits. After a stretch along waterways and canals you reach summit two (Corstorphine Hill), from here you will join the union canal before heading up the steps to the third summit (Craiglockhart Hill East). From here the route heads to it’s most southern point at the top of Braid Hill, your fourth summit. Your views from here will take in the entire route, and framed in the centre of your view will be Edinburgh castle, dominating the horizon. Your next stop will be Blackford hill and the royal observatory (summit five). You then head westwards towards the extinct volcano of Arthur’s Seat that sits perched, overlooking the entire city. After the steep ascent to the top of summit six, you will be glad of the welcome gradual descent down to the palace of Holyrood.  After stopping for photos at the palace gates there is the final summit of Calton Hill where you will get to celebrate with incredible views along Princes Street, Edinburgh’s old town and the castle.
