1 HR 3 MINS
With only 3 hours sleep the night before, a very busy stressful day at work and the weather was incredibly hot and sunny, I manage to do it in 1 hour which is pretty good except that I was able to do it in under an hour last week! My breathing never steadied and I was growing tired very quickly. It wasn't only me, the others also had problems coming up. I guess I should still be proud.
