Mt Leinster Challenge

This is a point to point challenge in which the runner hits five Blackstairs summits, including Mt Leinster. The runner chooses their route between each summit. 

The challenge begins when the runner leaves Shannon's Lane sign post and it finishes when the runner arrives back at Shannon's Lane sign post. Depending on runner's route choice, the challenge is approximately 25k/1200m. The summits that need to be visited are Clorogue More, Black Rock, Mt Leinster East Top, Mt Leinster and Knockroe. There is no time limit on this challenge. Fiona Ní Mhulláin created this challenge and was the first to attempt and finish it on 5th June 2022.

Rules and guidelines:

  • Athletes must carry coat, hat, gloves, foil blanket, first aid kit, whistle, map/compass and/or gps for the duration of the challenge.

  • Runners must announce their attempt to IMC, prior to their run. 


  • GPS devices are allowed and pacers are allowed. The same pacer(s) can not complete the length of the challenge with the runner. Otherwise, it will be considered a team completion. 

  • If a runner chooses to attempt their challenge unsupported and/or solely with map and compass navigation, then this will be specified on the results page. 

  • Completed challenges will be validated when a runner/s supply IMC with a gpx of their run. If a runner chooses to navigate solely via map/compass, and they would like this to be specified in their results, then they will have to supply gps tracking link from their run. 


This is a personal challenge. IMC's only involvement is to agree to record attempts. Neither IMC, its servants or agents can accept any responsibility of any nature or kind for loss, damage or injury suffered by a participant who takes part or attempts Mt Leinster Challenge. Each participant takes part at their own risk and is fully responsible for their own safety, support and equipment.
