So I had back surgery back in March which made me gain an additional 25 pounds, but thats just the cherry on top of my ice cream. I was already about 75 pounds over weight which brings my grand total to about 100-110lbs of excess fat or 300 big macs which ever comes first.
I used to ride 200-300 miles a week until 2005 when i moved away from college and got a job, (insert excuse here)

So now that Ive average about 25lbs a year in weight gain I think its time to get back in shape before I get diabetes since it runs in my family.
So I drive to the storage and get my two bikes out drive to my local shop and purchase everything I need to tune them up. Which got me thinking about a few questions.
The bikes in question are a 2003 KHS Flite 300 Road bike and a 2003 Dimond Back hardtail (I think its a Reponse but i cant recall) MTB.
Back in college I weigh-in at approx 160 and now im at 275.
1. Should I still ride my road bike? I dont want to put too much strain on it.
2. If so, should I choose to ride the road bike instead of the MTB to maintain a higher cadence which will allow me to lose more calories?
3. If you guys don't recommend I ride my road bike. Should my next goal be to ride as long as I can maintaining a high cadence instead of going for distance or time.
4. Saddle soreness is HORRIBLE; I dont recall any of that it almost feels like I ran backwards through a corn field. I tried switching to a wider seat but it worst on my inner thighs so Ill stick to a smaller seat at hang in there with the pain.
I did take the MTB out for a spin three times last week but I was super slow and when I mean slow I mean less than 8 miles an hour. So it took me 2 hours to do 14-16 miles and Im going to be honest I took a Slurpee break at around 10 miles, hey im fat

but lets not focus on the wrong part of the story.
I remember part of what I loved cycling so much was the speed and remember riding and averaging 20-23mph and not even trying. So trust me when I say Im a little frustrated with myself trying to relearn the process. Any how im sure ill re-kindle my love with cycling again when it doesnt hurt my body and soul when I ride. Thanks everyone.
