doohickie - I guess adding 10 miles in each direction is quite the increase. I used ti ride 17 each way. each ride was an epic journey. I only ever did 2 full 5 days weeks at that distance but I'm a better rider now. I'm down to 13 miles and some days I'm downright giddy at the shortness of the ride, but not lately, not in this weather. I too have some hill climbing on the way home within the 1st 3 miles. It's a drag but I know where they are so I plan for them and make sure I'm in the correct gear, etc. you're probably gonna see some physical changes and may have to change your nutrition planning for the additional miles.
