Just a quick one for the masses.
I’ve been doing my TT efforts in the dark at 5:30am-5:45am here in NZ at sea level.
My times have been slower than I would have bought, but my power is better than ever.
Is the air denser early in the morning compared to later in the day.
Both days the weather and wind has been very similar . Equipment/position allotetty much the same.
It just seems slower, any thoughts?
