Race Guide

It’s the world’s most notorious ultramarathon – and shrouded in secrecy for good reason due to the delicate ecological nature of Frozen Head State Park in rural East Tennessee, meaning spectators are not encouraged.

But last year it made global headlines like never before. Chiefly because of what Jasmin Paris achieved in becoming the first woman to finish the 100+ mile event inside the allotted 60 hours (with 99 seconds to spare!). She was one of a record five to make it round, meaning that only 20 different people have finished. Just to put that into context, 24 humans have visited the moon!

After fevered anticipation this year’s race got underway at a latest-ever local time of 11:37 on Tuesday 18 March. The 40 invited runners obviously knew the start date but not the time – only that it would begin at some point between midnight and noon in Tennessee so it went down to the wire!

That was heralded by the blowing of the conch by new race director Carl Laniak which signals an hour to go and a scramble to get ready, including grabbing a watch from race creator Lazarus Lake.

GPS is not allowed – it’s map and compass and a desperate search for pages of a book on each 20-mile loop which each have to be completed within 12 hours. Click here for more details on the nuances of the event but the ultimate aim is five loops within 60 hours to join the select list of finishers.

Regarded as one of the toughest running events in the world, will it be even more challenging 12 months on from last year’s record number of finishers? Time will tell.

Barkley Marathons live updates

There is no website or social media page, let alone live streaming, and no GPS devices are allowed so it’s a very different version of ‘live tracking’ for this one.

The one semi-official way to follow what is happening is via @keithdunn on his X feed (and also on Bluesky) which we’ve embedded below (just click the ‘X FEED’ button to view).

And we’ve collated all the information to keep you in the ‘loop’ throughout.

Loop 1 | Loop 2 | Loop 3 | Loop 4 | Loop 5

NOTE - the X (Twitter) timeline functionality doesn't appear to be working on mobile but is ok on desktop / laptop devices. This appears to be an issue with X itself

Who's taking part this year?
It's been as tricky as ever to decipher but we look to have at least two former finishers - and the overall winner of last year's Dragon's Back race.

The conch is blown and cigarette lit!
It went down to the wire in terms of the daily midday cut-off but the 2025 Barkley Marathons started at 11:37 local time on Tuesday 18 March.

The Barkley Marathons

start list

There’s no public start list and it’s only as the race develops that pieces of the jigsaw start to emerge.

Usually by winning the Big’s Backyard ultra you get a spot – that was the case with Harvey Lewis last year, but seemingly not this time around for Scott Snell – click here for more detail on that.

Another route is first male and female at the Barkley Fall Classic which in 2024 were England’s Tim Landy and American ultrarunning and Toughest Mudder / Hyrox star Kris Rugloski, who also won that event the previous year but missed the Barkley because of an untimely injury. This time she said: “I’ll be back this spring for the big dance”.

As for the rest we’ve got at least two former finishers, last year’s Dragon’s Back winner, a two-time Spine Race winner looking to follow in Jasmin Paris’ footsteps plus a few other names which have emerged and you can keep track of the latest ones via this post.

Notable runners

Route

The Barkley Marathons is made up of five 20-mile loops with more than 54,000 feet of ascent (that’s nearly twice up Mount Everest).

Each loop starts and finishes at the fabled yellow gate where competitors and support teams make camp and the runners have 12 hours to complete each loop.

The first loop is clockwise and then it alternates until the fifth and final lap. At that point the first-placed runner chooses which direction to go, with any other runners alternating so they are more likely to have to run separately.

In reality – though we don’t know for sure as there’s no GPS allowed – the loops are more likely closer to 26-miles long, meaning that anybody who completes all five will have covered around 130 miles. Any runners who manage to complete ‘just’ three loops inside 40 hours are awarded ‘fun run’ finisher status.

The route changes every year and it is near impossible to review – runners are shown a map the day before. Roughly 80% of the race is off-trail and there are no aid stations – just two water points.

And the difficulty of each loop can’t be understated, with incredible climbing and navigational challenges and all through thick and sharp briars.

The weather too will play a pivotal role – click here for the latest forecast which sounds very, very mixed for Thursday.

Each competitor has to find books hidden around the course and tear out the page corresponding to their race number. Failure to present a page from every book at the end of each loop results in disqualification. The book titles have become part of Barkley folklore and previously included Death Walks in the Woods, The Valley of Death, Almost Home, The Body in the Woods, Fool, The End, A Week in the Woods, and The Idiot.
