Very much depends on how hot it is inside and thus how easily Baby Roadrider400 falls asleep.What time do you lot go to bed?
If getting up at the usual 5:15am (on ride days) then I aim to be asleep by 10:30pm latest. Saturday just gone I probably didnt fall asleep until 11pm though.
I only ride once a week at the moment, aside from the short commute on my hybrid so one day with a shorter nights sleep isnt a big deal, and can always find 30 minutes for a powernap in the afternoon if really needed.
Knowing I am off for a long summers morning bike ride means getting out of bed is really easy, then one coffee and im fine.
