Just take the distance divide by the timing you have to pass and you'll get the average speed of the treadmill.
Taking 2.4 in Safra is more comfortable, got aircon, got TV to watch while running, got music, threadmil can adjust speed.
But I find the killer is the constant gradient set on the threadmil, after a while you ankles get really strained. So if you did
not train you legs, you might have a difficult time running on the constant 'slope'.
Last time this super garang young and dangerous PTI say he want to discount my attendance because I can't "run faster than the fat guy in front".
He was lucky to have backed down after that; else he will have kena complain by me for abusing his authority. Who says that fat people will always run slowest? Also, I'm pretty sure there's no authority to say he can discount people's attendance for not running fast enough to his standard
But that's at Bedok. I'm no longer doing IPT there because Maju opened and its nearer my home
