Stair Climb Training

I have found a taller HDB block at the junction of Alexandra Road and Commonwealth Ave. It is 40 storeys tall. I went up, take the lift down, walk up again, take the lift down and walk up to the 24 floor for a third time. Totally, I covered 101 storeys. I believe each storey is about 3 meter +, therefore, I totally covered more than 303 meters.
