I thought It would be worth to mention that... (that I'm not completely CG geek) that I took part in event called "BiegnijWarszawo" (RunWarsaw).
It is the biggest annual fun run in Poland. wiki.Biegnij_Warszawo
It took me about 48 minutes (47m46s) to do the job (10km) which resulted in 1497 among 9774 people... so I think it's not that bad.
As you can see I do not spend all of my free time on the computer... just most of it ;)
