5' 11" 250lbs. Had not ridden in 25 years

First time I rode 5 miles I almost puked out my liver, my butt ached and I couldnt feel the sausage or beans.

Last Saturday I rode 25 miles and felt like I could have gone more, and I barely feel the seat anymore, well, only after the second hour or so. I have been on and off over the past couple months and only just now getting more consistent. Hoping to ride my age (40) in another couple weeks and work my way towards 100 before the middle of the year, if only I can find somebody as crazy as me to partner with.
