The International Trail Running Association (ITRA) Performance Index is a ranking system designed to evaluate and compare trail runners globally. It provides a standardized measure of an athlete's performance based on their results in official trail running events recognized by ITRA. This system helps runners, coaches, and race organizers assess an athlete's skill level and is also used for entry qualifications in prestigious races like the UTMB® (Ultra-Trail du Mont-Blanc).
- What’s your secret? - I am just gonna keep running… Cliff Young I will write this post in English. Actually, I will mostly just re-print information from several sources, but I will show all references, in order not to incur in plagiarism. This is the story of an ordinary man who performs extraordinary feats. His name was Cliff Young, and he was the least likely hero that any Nation could come up with. "Albert Ernest Clifford "Cliff" Young , OAM (8 February 1922 [1] – 2 November 2003 [2] ) was an Australian potato farmer [2] and athlete from Beech Forest, Victoria . Born the eldest son and the third of seven children of Mary and Albert Ernest Young on 8 February 1922, Albert Ernest Clifford Young grew up on a farm in Beech Forest in southwestern Victoria.

In a world drowning in contradictions, doubt has become the only constant. Verena Solis, a journalist searching for truth, stumbles into a system designed not to silence, but to smother. Here, certainty is never banned — it is buried beneath noise, questions, and endless multiplication of versions. As protests collapse into paradox, as science is reframed into spectacle, she must decide whether truth can still survive when every fact is met with a thousand doubts. Atmospheric, unsettling, and urgently relevant, The Ministry of Doubt asks: what if ignorance wasn’t an accident, but the most powerful weapon of all?
Why Going to the Moon Is Mostly a Problem of Falling Correctly The reentry. Physics & Space Why Going to the Moon Is Mostly a Problem of Falling Correctly The orbital mechanics, velocity management, and controlled descent behind lunar missions April 2026 The Moon — 384,400 km away, reachable only by falling correctly. A mission to the Moon looks, at first glance, like a story of brute force: a giant rocket rises, crosses the void, lands, and returns. But the real story is far subtler. Moon travel is not primarily about going upward — it is about speed, timing, gravitational fields, and controlled falling. Every phase of the mission, from launch through cruise, descent, and reentry, depends on using physics not to defeat gravity but to cooperate with it. The distance from Earth to the Moon — roughly 384,400 kilometres on average — is not the primary obstacle. The rea...
Primeiros 100 km da prova, até a bateria do Garmin morrer... Link para o Strava (carregar na imagem): Lector in fabula Sempre preferi os loucos… Abro os olhos sobressaltado! Onde estou eu? Como vim aqui parar? Olho lentamente em redor… aos poucos as imagens vão-se fixando e a memória vai retornando... Estou na Ilha da Madeira, a subir vagarosamente para o Pico Ruivo. Devo ter cerrado os olhos momentaneamente e passado instantaneamente pelas brasas. Que horas são? Olho para o Garmin. São 11h40. Ainda só estou a subir há 20 minutos. Tocados pelo fogo. O truque é nunca parar. Custe o que custar, continuar sempre a colocar um pé adiante do outro. Subir degrau a degrau. É como andar de bicicleta. Se pararmos caímos. “Os que levam a vida inteira como alcoólicos e neuróticos são mais interessantes, as pessoas falam deles e contam as suas anedotas, enquanto os tranquilos só fazem o seu trabalho.” - Joyce Carol Oates Esta subida, este quilómetro ...
O Grande Debate: Neoliberalismo em Perspetiva Vultos. Ensaio · Economia & Política O Grande Debate do Neoliberalismo Entre a promessa do mercado livre e as fraturas da desigualdade — uma análise das ideias que moldaram o mundo contemporâneo. ↓ scroll para ler Introdução O que é, afinal, o neoliberalismo? Poucas ideias na história recente geraram tanto debate como o neoliberalismo. Para os seus defensores, representa a melhor via para a prosperidade: mercados livres, Estado mínimo, iniciativa privada como motor do progresso. Para os seus críticos, é um projeto político disfarçado de ciência económica — uma engrenagem que concentra riqueza, corrói democracias e transforma cidadãos em mero "capital humano". [1] O termo nasce nos anos 1930, no Colóquio Walter Lippmann em Paris, como tentativa de repensar o liberalismo clássico. Mas é a partir das décadas de 1970 e 1980, com a ascensão d...
How long does it take to run a marathon? The answer depends entirely on who you ask. The chart below uses a violin plot to show the full shape of the finishing time distribution — not just an average, but the entire spread from elite runners to first-timers.
Robert Sapolsky: The Biology and Psychology of Depression Robert Sapolsky, a renowned neuroscientist, primatologist, and author, has extensively explored the biological and psychological underpinnings of depression. His research and writings synthesize findings from neurobiology, endocrinology, and psychology to provide a nuanced understanding of this complex and often misunderstood condition. Sapolsky’s insights emphasize that depression is not merely a psychological state or a reaction to adverse life events but a multifaceted disorder deeply rooted in the biology of the brain and body.
