This will be a true test of mental and physical resilience. Running a marathon is tough, but doing it 1,120 metres below sea level, in total silence and darkness, will push participants to their limits. This is about more than breaking records - it’s about proving what’s possible when we dare to push beyond our perceived boundaries and into the unknown.
