King of the Mountain on Sunday, 20 May 2018 is a 16.1km race starting from Helena Valley Primary School and finishing at Fred Jacoby Park in Perth, Western Australia.
This is a cross-country event on the tracks following the Helena River from Helena Valley to Mundaring Weir. There are at least two water crossings where you can expect to get your feet wet - especially if we have had a few days of rain in the lead up to the event. Spectacular country and a feed at the end of the run.
This event is organised by the West Australian Marathon Club, but you do not need to be a club member to participate.
