First of all, the athletes out-trained the distance years ago. In that sense, the mighty marathon has been brought to heel. No longer a spirit draining test of endurance, today the marathon has been reduced to just another speed event contested over a longish distance. It’s no longer, runner beware. It’s distance be damned!

We saw a reflection of that again this weekend when Ethiopia’s Yomif Kejelcha won the Valencia Half Marathon In 59:05. A generation ago you would never have seen an athlete who set an indoor world record in the mile in March (3:47.01) transfer so fluidly to a sub-60 half-marathon in October of the same year (see list below).

Attitudes about the challenges in distance running have simply changed along with many other factors that continue to make headlines in and out of courtrooms.

These days for the marathon to grow its fangs back requires severe weather. And even then – as we saw in Doha at the World Championships in September – the very top echelon of runners are merely slowed rather than halted.

This coming weekend in New York City, the marathon will once again be finished by 95+% of its 50,000 starters, while up front a handful of contenders will race the entire distance and seem ready for more if the necessity arose.

To all of that, we now add a better mouse trap, the Nike Vaporfly shoes. This past weekend in Frankfurt, we witnessed a final four of identically garbed and footed runners battling into the final kilometer before a champion was decided.

Final four in final sprint in Frankfurt.

2. Dawit Wolde ETH 2:07:10
3. Aweke Yimer BRN 2:07:12
4. Martin Kosgey KEN 2:07:20

As long as all wore the same gear, then what ensued was indeed a test to determine who amongst them was the better athlete. But for those employing any other footwear than Vaporflys, the route was not level. The ones wearing the better energy transfer mechanisms were in another class. A different metabolic cost per stride was in play. Continue reading
