<human>: So My roommate has been really supportive of me losing weight (down around 25 pounds in 7 weeks).  He's a super athletic guy that went to a 10 week training camp for the marines this summer.  He's thrown around the idea of going on a run together but I've always been to self-conscious that I'd be too slow for him since he's in such good shape.

After weeks of pushing myself with working out I finally took him up on his offer (but told him that I'm just going to go my pace so I don't tire myself out trying to keep up with him).

We went on a 2.2 mile run and I completed it in 23 minutes and 53 seconds.  About half way through our run he made a comment to me saying he was really surprised at how well I was keeping up.  After the run he gave me a high five and told me he didn't think i could run that far and long without walking AND making it under 24 minutes.

I knew I could do the run that quick, but having him be so surprised and tell me that I'm doing awesome with working out and losing weight felt really good, and now he's going to tell all my friends that don't believe me when I say I go running that I actually kick some ass for my weight.

Oh, and the main reason that he was so impressed was that I did this all while weighing 280lbs (down from 305).  

To top it all off I'm going pants shopping tomorrow because none of my pants fit me anymore.  Today was a good day...

Can you condense the text into three sentences or less?
<bot>: Went running with my roommate (2.2 miles) and finished in 23 minutes 53 seconds.  He was really surprised and gave me a big confidence boost for my workouts that I'm accomplishing a lot.
