So many great answers already while I was sleeping 
but again what´s 100k or 200k compared to 100 mile/km ride?
So now I can tell that I'm going to do a 3/4-century (70 km) and a 5/4-century (134 km) in June and that's about all the organized rides back here. Riding in Finland is cool because there are not that many cars or people and the bike roads are usually kept in pretty good condition and they are all over the place. Finland is pretty flat country but we do a just a couple or decent hill even in my hometown. The riding season for me at least is from mid-April to mid-October. Rest of the year is too snowy.
thanks for the clarifications to everybody 
Oh btw peloton is a Finninsh word as well! I got a bit confused since here it means fearless.
