08/11/2016: Update:  For FKT credit the following criteria must be met: 

1: Prior announcement of your attempt must be made via the Issy Alps FB page. Join the group here. State your support format and distance.  Unsupported, Self or fully supported. There is no dropping down a distance or upping a distance. If you announce 50k unsupported then that’s what you will get credit for. Even if you decide you feel great and want to do the 100k or even 100m distance. So choose wisely.

2: A tracking device such as a SPOT or Delorme along with a link to your device. GPS tracks from a Suunto or Garmin will also be accepted after review.

3: You must stick to the original course. Please take a look at the maps section of the site for details. Example: You must use the old Mailbox Peak trail to go up and down. Using any alternate route will void your FKT credit. This also applies to non FKT attempts. Trying to keep track of all the route variations that folks are taking is becoming overwhelming. In short, stick to the original route and you will get credit!


The main objective of this site is to promote challenging courses that will test the mental, physical and emotional limits of each participant. These are NOT races but feel free to attempt an FKT for any of the events on this site.

For FKT verification, use a  gps tracking device like a SPOT (preferred device plus the internet audience can follow you too!) which will record your route and time. You can also use a smartphone with gps recording capabilities or a watch such as the Garmin Fenix or Suunto Ambit that will also record your tracks which you will later submit for verification. Make sure you have enough battery power or the ability to charge your device in the field.

There are three FKT categories.

  • Supported means you have a dedicated support team that meets you along the way to supply whatever you need. This generally allows for the fastest, lightest trips, and for an element of camaraderie and safety, since someone knows about where you are at all times.
  • Self-supported means that you don’t carry everything you need from the start, but you don’t have dedicated, pre-arranged people helping you. This is commonly done a couple different ways: You might put out stashes of supplies for yourself prior to the trip, or you might just use what’s out there, such as stores, begging from other trail users, etc.
  • Unsupported means you have no external support of any kind. Typically, this means that you must carry all your supplies right from the start, except any water that can be obtained along the way from natural sources. This approach has also been termed “alpine style”. Unsupported also means unaccompanied!
