Just one, usually.

Just one, usually. Sometimes two, but it was rare. Running one single lap along the border of a lake in the outskirts of Toulouse sufficed to get me tired enough not to attempt a second one. Back then - I am talking 1994 here - I was proudly convinced it was a decent distance but Google Maps has righted my wrong - barely 3.5 km, coming well too short to anything satisfactory. Truth be told things have now changed, and for the best, to my utmost surprise. I am now able to run 10 km distances on a regular basis, say three times a week, and I'm seriously considering another attempt at a half-marathon race. I wonder what has actually made possible to accomplish such a remarkably higher goal. Perhaps aging is one of the keys. Being now 15 years older has probably improved my endurance, has turned me less anxious to short-term achieving a long-term goal. This is a simple guess though, yet other than this I'm at a total loss.
