I experienced 8ft wall at Spartan BEAST in Niigata pref, Japan. 8 ft is over 2.4 meters. Women is permitted to use assistance blocks, but men is NOT permitted to use them. So, small person like me was very hard.
Maybe not only jumping power but also arm power is needed for me. I could NOT clear it at Spartan BEAST in Niigata perf. I’d like to clear it at next race.
