After several marathons and up to 70k ultras I decided to further explore my capabilities. This time I would like to try how much I can run in 12-13 hours i.e. from early morning till late evening, hoping that I can get as close to 100k as possible. Similarly to my 50 and 70k experiment, this one is again going to take place in the Hvezda Park, Prague. By doing this I would like to express my appreciation for Team Elijah's Star.
