π WATCH: The Science of Running Negative Splits
Jack Daniels, the Olympic medalist turned exercise physiologist whose training formulas reshaped modern distance running, died September 12 at the age of 92.
His wife, Nancy, said he βdied happy after watching the Green Bay Packers win last night,β a fitting end for a man who once tested the Packers as a graduate student at the University of Wisconsin and remained a lifelong fan.
Sabastian Sawe, the reigning London Marathon champion and fastest marathoner in the world this year, has announced a self-imposed anti-doping protocol in partnership with the Athletics Integrity Unit (AIU) ahead of his upcoming appearance at the Berlin Marathon on Sept. 21.
The move is unprecedented, and importantly, voluntary.
Pacing isnβt just a skillβitβs a strategy that can make or break your race. Get it wrong, and you risk crashing before the finish line. Get it right, and youβll power through the final stretch feeling strong, confident, and in control.
The golden rule? Start conservatively, finish strong. And the longer the race, the more critical that becomes.
The New York City Parks Department is trying to put an end to a growing tradition among the cityβs running community, warning organizers of βThe Last 10β pre-New York City Marathon shakeout runs that any unsanctioned event entering Central Park this October will be considered a direct violation of park rules.
By the time the sun rises over Tokyoβs National Stadium on Saturday morning, over 2,000 of the best athletes in the world will be ready to unleash nine days of championship-level chaos.
The 2025 World Athletics Championships, taking place from Sept. 13 to 21, mark the return of the sport to a city that last hosted a global meet under the eerie silence of the 2021 COVID-delayed Olympics. β This time, the stands will be packed, the weather will be intense, and the stakes couldnβt be higher.
Athletes use various training methods, such as RPE (rate of perceived exertion), specific paces in minutes per kilometer or mile (calculated after a speed test like a 3K or 5K), and target heart rate zones, to lead them to their goals.
Each method has pros and cons, and choosing which to use will depend on each individual athleteβs current specific training plan, phase, and goal. β In this guide, we will talk about heart rate as a run training method, calculate your running heart rate zones, and examine the factors that can affect this metric so you can decide if itβs the correct training methodfor you.
