So true. When I compare my times on a given route, conditions are a major factor.
There is one route I use often, when there is no wind. The 1st 20 miles climbs 1000ft(I know that is nothing),and the final 30 has some stoplights that can effect the average speed.
It's normal for a 20mph average, but I'm very happy when I push it and flirt with 21mph.
