I had participated in many races before, but never for vertical marathon.
What's different of Vertical Marathon with other races? The race distance of Vertical Marathon is counted by floors instead of kilometers.
Initially I was predicted myself can run non-stop to 30th floor, but actually I just able to reach half of it. From 15th floor onwards, I used "walk". Walk... rest... walk... rest... walk... finally I conquer the 73-storey hotel with the time of 18mins.
