Reservoir Deck at MacRitchie Reservoir (as shown below)

Event Format (Individual Category)

  • Participants must start & finish at the Reservoir Deck at MacRitchie Reservoir.
  • Participants must reach their designated Checkpoint (based on the category/distance selected) and make U-Turn back to the Finish venue.
  • When you arrive at each Checkpoint, you MUST 'Check In' with the volunteer.  Your 'check in' time will then be captured.  If you do not 'Check In', your time will not be captured.
  • Usage of any form of public/private transport modes to assist with your completion of the event will result in disqualification and you will not receive the e-certificate.  We believe in your integrity.


  • Only participants of the following categories can have an "Official Pacer" who will have an event Bib on him/her which allows him/her access to the food/drinks/assistance at the official support stations.
  • - 74km
  • - 101km 
  • - 100 miles
  • We recommend having 1 x Pacer with you, to guide/encourage/take care of you.
  • You can have only 1 x Official Pacer at any point during the event and he/she will have 1 x Bib Tag with the text "PACER".
  • The Official Pacer need not be with you throughout the event.  He/She may accompany you at any point of the event, but he/she must make his/her own way to your location/Checkpoint which you require him/her to start pacing with you.
  • You may appoint anyone whom you deem suitable to be your Official Pacer.  There is no need to register your Pacer with us.
  • Your Official Pacer can utilise the support stations at the Checkpoints but he/she must have the "PACER" Bib Tag.  We are unable to provide support to any unofficial Pacer(s).  Please do not take any drinks/food from our Checkpoints & share with your group of unofficial pacer(s) who are with you.  This practice is unacceptable & unfair to other participants as it is a paid event & logistic supplies are catered only for paying participants & 1 official pacer at any point during the race.  We will not hesitate to disqualify(DQ) any participant who has unofficial Pacer(s) taking food/drinks/any other assistance from our Checkpoints.
  • Your Pacer can carry your race items on your behalf.  There is no requirement that you must carry everything on your own.
  • You may have a group of Pacers, doing their pacer role on a rotation basis, e.g. 1 Pacer from CP 5 to CP 6, and another Pacer takes over from CP 6 to CP 7.  But the next Pacer must take over the "PACER" Bib Tag
  • We will not provide any form of support for anyone who does not have the "PACER" Bib.  Thank you for your understanding as we will not cater resources for unofficial Pacers.
  • If you have appointed a pacer, you may collect your Pacer Bib Tag when you collect your own Race Bib Number Tag.  You may make your own arrangement to pass the Pacer Bib Tag to your Pacer.  We will not issue the Pacer Bib Tag to any self-appointed Pacer.
