Newsletter #843: Saturday, 20th June 2026


Hey runners, in today's newsletter, the headlines stretch from the world's fastest 150m ever run to the dairy farmer who just conquered 268 miles of British wilderness, with a coaching legend's 95th birthday in between.

Noah Lyles posted the fastest 150m ever run, clocking 14.67 in Ostrava to hold off teenage rival Gout Gout and beat Kishane Thompson's mark from earlier this spring. On the ultra end of the spectrum, Irish dairy farmer Ed Payne returned to the brutal 268-mile Summer Spine Race a year after dropping out and won it with most of the Cheviot Hills between him and second place. And Hal Higdon, the coach whose training plans have introduced a generation of runners to the marathon, just turned 95 and is still going.

Olympic medalist Jenny Simpson is showing encouraging signs the day after her track collapse, with Fleet Feet saying she has already asked about her mile time. World Athletics has also opened a new study called CARES, gathering data on pregnancy and the return to elite competition, with responses due September 30. Tudor has signed four of the world's top trail runners, including Courtney Dauwalter, putting mechanical watches on wrists that race for days at a time. And Canadian Olympian Rory Linkletter cracked the top 15 in his very first elite mountain race, finishing 14th at Broken Arrow Ascent.

We've also got a look at why your summer pace has slipped (spoiler: it's the heat, not your fitness), and the realistic odds of getting into London via the new Double Ballot, plus every other route in if you don't.

And as always, we round things out with the practical stuff: how to actually break in new running shoes, why your legs feel heavy and how to fix it, a runner's guide to HRV, and how many calories you really burn out there.

The Wahoo KICKR RUN — built for serious runners

If you've ever resented your treadmill for feeling more like cardio equipment than a real training tool, the Wahoo KICKR RUN is the antidote.

The KICKR RUN pairs natively with COROS watches so your indoor miles carry the same weight as your outdoor ones, runs on a powered RunFree mode that adapts belt speed to your pace automatically, and is engineered around runner-specific geometry: long deck, soft landing, near-silent motor. The most thoughtfully-designed treadmill we've seen for serious runners.
