i try not to pay too much attention to average speed since it depends on so many things
yesterday i rode my road bike for 26 miles- the majority of the ride was between 19-20 mph but when i arrived
at home my average was 17. this i think had alot to do with the number of traffic lights i hit and having to slow down and
get back up to speed since very few of them can i run. of course it could have alot to do with me being
extremely slow, who knows
