“As I stood at the Tahoe City transit center waiting for the final minutes to tick down before 6am…”

Adam Kimble made his second attempt to better Kilian Jornet’s 2009 supported Fastest Known Time (FKT) of the *Tahoe Rim Trail (TRT) in California/Nevada. He first completed the 171-mile route in October 2019. He followed the same route as Kilian, running clockwise from the bridge at the Tahoe City Transit Center.

“My crew met me at various trailheads for support: Brockway Summit, Tahoe Meadows, Spooner Summit, Kingsbury Grade, Big Meadow, Echo Lake, and Barker Pass. It was a really hot weekend for Tahoe (getting into the mid-80’s), so I also had some friends meet me at various points on the north and east side of the lake (e.g. Watson Lake, Relay Peak, Tunnel Creek), where there is little water to filter, it’s highly exposed and extra hydration was crucial. The first 20 miles I ran solo to Brockway Summit, and then from there I was accompanied by a pacer for each of the following segments all the way back to Tahoe City.”

July 18th: Adam returns to the Tahoe City Transit Center (171 miles) at 7:12 PM (37h12m15s), setting a new Fastest Known Time of the Tahoe Rim Trail!

*The Tahoe Rim Trail is about six miles longer in 2020 than it was in 2009

What is a Supported FKT?

According to the Fastest Known Time website: “Supported means you have a crew that meets you along the way. This can range from one person handing you water once, to an entire team that accompanies you the whole distance giving you everything (except physical assistance — FKTs are self-powered). Whether it’s just once or continuously, any support at all means it’s a Supported trip. Supported can enable the fastest trips due to the ability to carry less weight.  To get a Supported FKT you also have to beat the fastest Self-Supported and Unsupported times.”
