​

Hey runners, in today's newsletter, Salomon just made a serious move outside of trail.

The French brand has bought the naming rights to the Ironman World Championship from 2027, taking over in Kona and picking up the exclusive footwear rights Hoka holds today.

Elsewhere, Megan Eckert ran her first race in 2016 and now holds the six-day world record, covering a distance no woman had reached and no man in the field came within 50 miles of. Doris Lemngole has turned pro with On after leaving Alabama with five NCAA titles and The Bowerman. And Tom Evans took on double Olympic mountain bike champion Tom Pidcock to the top of Snowdon.

And as always, we round things out with the practical stuff: how long it really takes to train for a marathon, how to safely increase your cadence, and what running 5K every day does to your body.

But its secret weapon, says senior editor Alex Cyr, is its unexpected comfort and cushioning. Unlike its predecessor, the Pegasus Plus 1, the 2 feels good on the feet, and can easily guide you through long workouts without battering your legs. Watch our full review on Youtube.
