Meet the trailblazers leading the way in FKT's for top hiking trails.

If you have ever hiked a trail and wondered how fast someone has completed it, read below and discover the fastest known times (FKT) set by ultrarunners for some of the most popular hiking trails in the USA.

Spoiler. Ultrarunners are fast.

As COVID continues to lead to the cancellation of running events around the world, the number of FKT attempts is on the rise.

Three women’s FKT records have been set in August 2020 - congratulations!

  • Liz ‘Mercury’ Anjos set the new women’s supported Appalachian Trail NOBO FKT at 51 days 16 hours 30 mins (completed 27th Aug 2020).

  • Summer Frazier set the new women's unsupported Mt Whitney ascent FKT at 3 hours 4 mins 46 secs (completed 27th August 2020).

  • Mikaela Osler set the new women's self-supported Colorado Trail FKT at 10 days 12 hours 36 mins (completed 9th August 2020).

FKT attempts involve no physical assistance, however there are three different categories of support:

  • Supported - if any form of support is received from a friend/family/crew member, the FKT attempt is classified as ‘Supported’.

  • Self supported - similar to supported, however the difference is that the support received was unplanned/received along the way.

  • Unsupported - you guessed it, no external support of any kind was received (e.g. everything required was carried, with the exception of water).
