For January, did a 100.08 mile urban ride in Southern California. Rode from home to my son's campus out in the suburbs and returned home. Route was mostly along bike lanes and about a third on Class I bike paths following LA's cement rivers. Not sure I can keep it up for the rest of the year. This was a pretty flat ride and it still took me 9.5 hours. Not too scenic but took some photos along the way. Unfortunately I can't post for another 7 forum contributions.
congrats! it will get easier the more you do it.
