Thanks all!

I'm thinking I might do something in between - increase my daily mileage as much as possible, and then get in maybe 3 or 4 really long rides in the weekends. Starting a ride before dawn was a good idea too - I commute all winter so I have a whole box full of various lighting configurations

So far this is all very hypothetical, my longest ride to date is 83 km (yesterday)... Nice ride! worked on riding "gently" and came back feeling very fresh and un-tired.
