Mount Kinabalu is near

Our training is climbing the 40th story stair HDB up & down three times a week!

For my Kk trip , I suppose to climb 2300 m high , it means 29 times up the 40th floor ! But I only did 3 times ..........😥

Perhaps we have to increase to 4 set of up & down climb and 2 times a week training! And may be we should load with 10 kg bag 

The timing for climbing up 40 story is 8 min and another 4+ min to climb down
