I made all the classic mistakes. I immediately went for 5 km, almost sprinting, immensely out of breath and full of pain in my lungs. My calves were cramping, I could taste iron in the back of my throat. But I made it out alive. And somehow I did it again a few days later. And again, and again, and again... This is almost 1,000 runs ago. Some of those runs were 2 km, many of 'em were 5K's, and the longest one was 146 km (never again... well... maybe)...
