...but is it faster to slow down for the entry/exit and drive straight down the middle, or to keep your speed up throughout and loop all the way down the tube? 


.
. Though in other hand, I might leave it as it would be now.
and if it starts around 18.00 UTC it has my vote 
~18 UTC = 20.00 Finnish time 
. I guess Tuesday and Thursday will be OKish. Maybe consider Saturday evening?
Sometimes im busy on friday nights, sometimes im not.. Atleast i dont have an early wake on saturdays
(if the race starts late)... Tuesday, thursday and friday has my vote
