I agree - it's great to see this forum!
I just laugh at myself... I half-commute. There is a park-and-ride halfway through my drive to work, so I ride halfway. It's not much... only 6.9 miles, so my commuting days log me a whopping 13.8 miles! (My husband regularly rides 50-75 miles, 4-5 days each week.) Oh well - I'm oddly proud of myself anyway. I started riding in July, and already feel stronger.
I just wish I could do it more days! I can't commute when I have appointments and seminars out of the office, so find that I usually can only commute 2 days each week. My goal, before the end of September, is to work myself up to full commute... that would be 27 miles each day!
I'm lucky... the commute in is mostly downhill. Of course, that means I have an uphill battle to make it home at the end of the day!
