The definition of madness is doing the same thing over and over and expecting a different result.

The same thing: Climbing three towers in London - The Scalpel, the Cheesegrater, and the Walkie Talkie - 475m of ascent in one day.

The expected result: No pain!

The Team:

Cengiz - "I'm not signing up for this again." *signs up for this again*

Bunmi - Purchase Ledger Clerk by day, stair climbing butterfly by night.

Jamie - Go high, go hard.

Darryl - "Can we use the lift?"
