Now we go.

How can you not be romantic about baseball?

What's the key to a fast marathon? A lot of "slow" miles. According to a new study analyzing 151,813 marathon performances, how runners distribute their training intensity is a key predictor of race-day performance. The study examined training logs from runners of all levels, grouping them by marathon finish time. Using a three-zone intensity model, researchers categorized workouts as: - low-intensity (Zone 1; below lactate threshold) - moderate-intensity (Zone 2; between lactate threshold and critical speed) - high-intensity (Zone 3; above critical speed) They analyzed how much time runners spent in each zone in the 16 weeks leading up to the race and how that related to their marathon performance. Here’s what they found: - Faster runners (finishing in 2–2.5 hours) trained three times more than slower runners, averaging 107 km (66 miles) per week. - The top performers spent ~67% of their training time in Zone 1 (easy effort), while slower runners spent less time in this zone. - The faster runners also followed a pyramidal training intensity distribution (Z1 > Z2 > Z3). This strategy, emphasizing high volume in Zone 1 with decreasing time in higher zones, was most common among the fastest athletes. What hurts performance? - Spending too much time in Zone 2 or Zone 3 was linked to slower marathon times. The findings align with broader endurance research, showing that elite athletes rely on high training volumes (the “80/20 approach") combined with strategic high-intensity efforts to reach their peak.

After spending some time last month listening to @AlexJSarama talk about the CLA in basketball, I’ve been thinking quite a bit on bucketing this approach for training throwers. New blog out now -go dive in. And yeah, it’s #good2learn criderperformance.com/blog/constrain…

'All probabilities are conditional on something, and to be useful they must condition on the right thing.' -- Frank Harrell

Constraints are always present. Self-organization is always happening under the current constraints. Constraints or self-org ≠ functional movement. Skill is a search. Functional problem-solving is finding the best fit for the athlete which might look diff than the ideal.

“I thought that if you wanted to win an audience over, you had to communicate certainty. Now I realize that’s actually backwards. “You’re more capable of winning over an audience if you admit to the uncertainty and fragility of your position.” Beautifully said.

A great case study of training general physical preparation broadly with two very different subsets of elite athletes, while individualizing their training just enough to avoid regressing their training to the mean @Canon_Reeder and @Wilson__Weber ⬇️

I’m super excited to announce that I'll be joining the @RedSox as the High-A hitting coach. Huge thank you to everyone @DrivelineBB. It's been an honor working with some fantastic people who taught me so much and gave me experiences I will never forget.

My man @ericjagers with some gas at the @WakeBaseball Bridge Seminar. Huge shoutout to @MikeMcFerran_ and the whole Wake staff for putting on a great event. Feels really cool to see the pitching world collectively coming together to continue to make hitters lives hell. Onward.

Pumped to announce that I will be starting a new job as AAA Bullpen Coach for the @RedSox! Can’t thank the guys @premierpitching enough for welcoming me into the family and allowing me to grow as a person and coach, but very excited to see what this next chapter brings! 🔴🧦

The #RedSox today announced that they have hired Andrew Bailey as the Major League club’s pitching coach.

Very excited to join the @RedSox #DirtyWater
