The heat is on!
If you have been preparing for the climb the last couple of months you should be in decent shape by now...but climbing 110 flights of stairs still isn't going to be easy (especially in bunker gear). You already know that our gear traps your body's heat and beats you down...making the trek even harder.
If you plan on doing the climb in your gear, don't let the day of the climb be the first time!
Caution: Climbing in gear should not be attempted unless you are healthy, fit and hydrated. Just as you would for the day of the climb, ensure that you have pre-hydrated, that you stay hydrated while you climb and that someone is with you. And just as the day of the climb, climbing 110 floors is not a race in practice...what matters most is that everyone finishes.
