26 marathons and 2 ultramarathons, at 65, in less than 2 months (May 11 - July 8, 2020)
to show the vocation and abilities of all humans to run marathons to stay or become fit, healthy and happy again, for free.


But, first we must recover our free will, because it’s the key to understand fully what we’re going through and to do what’s good for us, before it’s too late, instead of relying naively on businesses or experts who are thriving on our extraordinary gullibility, our fears, our desperation, our chronic diseases or viral pandemics, etc. That’s the whole point of my book:
Running Barefoot for Human Survival.

One of the lessons that we should learn from the COVID-19 pandemic is that race cancellations can’t prevent a runner, whose purpose is only to stay fit, happy and healthy, from running even more marathons or ultramarathons, moreover, for free, at home, at the holiday destination, etc.

A further lesson is that, at the end of the day, all marathons are equal, because the distance is always and everywhere the same, i.e. 42.2 km or 26.2 miles. The only difference is that it’s undeniably more challenging and more natural, but also more rewarding, to run a marathon or a 90 km (56 miles) ultramarathon without any assistance and without a crowd of supporters, which enjoyably brings us closer to our roots as hunter-gatherers.

The human body is not designed for our lifestyle. We’re born to run barefoot to be happy and healthy and boost our immune systems. And that’s crucial, since prevention is the free, safe and most effective solution to many diseases and pandemics, including obesity and COVID-19.

Le corps humain n’est pas conçu pour notre mode de vie. Nous sommes nés pour courir pieds nus pour vivre heureux et en bonne santé et renforcer notre système immunitaire. Et c’est crucial, car la prévention est le remède gratuit, sûr et le plus efficace contre de nombreuses maladies et pandémies, y compris l’obésité et la covid-19.

El cuerpo humano no está diseñado para nuestro estilo de vida. Nacimos para correr descalzos para ser felices y saludables y fortalecer nuestro sistema inmunológico. Y eso es fundamental, ya que la prevención es la solución gratuita, segura y más eficaz para muchas enfermedades y pandemias, incluidas la obesidad y la COVID-19.
