Looking at the LA28 schedule, 10k / marathon double is super viable. Just sayin' 👀

Should you run at a constant effort or a constant speed, if you are doing an out-and-back loop with a strong wind? Turns out...it depends! *Usually* constant-effort is better, but at slow running speeds with very strong winds, constant-speed can actually win!

Amazing gem from the old internet: "My Uncle from Africa," a blog about the Swedish-Finnish coach Onni Niskanen, who moved to Ethiopia to help develop athletics in that country after WWII and became the coach of Olympic Marathon champion Abebe Bikila ulfniskanen.wordpress.com

(the >20 mph story is very funny: the reason the predicted energetic cost is too high is that, in extreme headwinds, people lean into the wind and use their torso like a wing, generating upward force that reduces the metabolic cost of running!)

How do I know my wind-adjusted pace calculators are accurate? Because they agree with real wind tunnel data in headwinds of up to 20 mph / 32 km/h!

Super exciting to see a global championship in India! With indoor/outdoor/cross/relay/road championships there are so many opportunities to make athletics a truly global sport

During his World Indoor Championships press conference, World Athletics president Sebastian Coe announced that the 2028 World Indoor Championships have been awarded to Odisha, India 🇮🇳, and that the 2030 edition will be held in Astana, Kazakhstan 🇰🇿. The Kalinga Indoor Athletics Stadium is the only dedicated indoor track stadium in India. Qazaqstan Indoor Track and Field Arena in Astana has hosted the Astana Indoor Tour meet as part of World Athletics’ gold-level circuit.

I'm working on a "track version" of my wind calculator & made an interesting discovery: for circular loops, the average effect of wind on pace doesn't depend on the size of the loop -- on a 2mi circular loop you just spend 2x the time at every point as a 1mi loop

(Also, since someone on ig asked about this: I shifted the calendar here to align with a US-centric season peaking in May/June; the original book obviously peaks in July/Aug for the Olympics etc)

Peter Coe's book "Winning Running" is one of the few resources that lays out *year-long* periodization schemes for middle-distance training. The real key here is the massive Oct-Feb base or "preparation" phase
