Equipment efficiency
Gearing
Tire size
Tire tread
Tire TPI
Tire inflation pressure
Type of hill (short & steep vs long & gradual)
Type of turf (Paved, limestone, hard pack, soft, muddy, snowy, etc...)

... Even emotional factors enter into it: Confidence, Aggressiveness, etc...

So, to the OP: What do YOU think the problem(s) is/are?
