Heart rate climbing on the run?


,

Hi runners,

Jessy here with newsletter #670! 🎉

Happy Saturday! ​
​
Here's what I have for you today
:

  • We dug through the chaos so you don’t have to. The discounts runners care about, the gear we’d buy ourselves, and a few surprises we didn’t expect to see marked down at all, these are the Black Friday deals that matter (and are almost gone!).​
    ​
  • If you care about shoes, this was the year to pay attention. Brands took real risks, foams got stranger and better, and a few models ended up shifting the entire conversation around performance. Our team breaks down the picks that actually shaped 2025.
    ​
  • Conner Mantz is ending his season early. After switching abruptly to cross-training and hinting at a mystery injury on Strava, he’s now confirmed he won’t race his late-season goal.
    ​
  • Injured? Bored? Or just… not in the mood? There are plenty of ways to build fitness without lacing up, and we highlight four surprisingly effective options that might end up becoming your new go-to workouts.
    ​
  • The steroid-friendly “Enhanced Games” just pulled off its wildest twist yet: it’s merging with a Hong Kong SPAC in a deal valuing the company at $1.2B.
    ​
  • Marathons are iconic, inspiring… and maybe not for everyone. This guide unpacks eight reasons you might actually be happier sticking to regular running, no medal required.
    ​
  • If your heart rate seems to have a mind of its own on long runs, you’re not imagining it. This guide explains the sneaky phenomenon behind the climb, and how smart pacing and hydration can keep your workouts on track.

​Our Team Picks The Best Running Shoes Of 2025​

Running shoes didn’t just get a little better this year, they got weird, creative, and genuinely transformative.

Our team tested everything from super-trainers to daily workhorses, and a few shoes ended up defining the entire year.

Here’s the list that actually mattered in 2025.

​US Marathon Champ Conner Mantz Pulls Out Of Next Race Due To Injury​

After weeks of quiet speculation on Strava, Conner Mantz has pulled out of US Cross.

The American marathon record holder says the nagging injury he hoped would “clear up” hasn’t budged, and his late-season plan to race is off.

His logs, 10 miles of running, hours on the arc trainer, told the story before he did.

Running isn’t the only way to get a great cardio session, not even close.

​Enhanced Games to Go Public in $1.2 Billion SPAC Merger​

Just days after losing its $800M antitrust case, the Enhanced Games is now planning to go public in a $1.2B SPAC merger, despite never having staged a single event.
