Thanks everyone for your support.
I got a big surprise during the race some hours into the race a fast finish guy approached me and it was Mr Ultrapetita!!! It was his first 24h he had only runned 100km before and he did relay well, (he dig go much longer then me also !!!
It was very nice to meet you in real life (if running around 390m track inside for hours after hours can be considered as real life...). And you made an excellent result, Congratulations!
As this was my first trial of 24h, I didn't have any targets in mind. Everything over 100k was positive.
After 120k I was ready to give it up and went to my sleeping bag for two hours, but luckily one of my running club mates didn't allow me to continue my "sleep" and I had to continue for the rest 8 hours.
Maybe next time I won't give up due to first signs of tiredness...
