Am I just really out of shape?

I agree with this. The first 15-20 minutes when the body is getting warmed up and the heart is getting up to speed you can often feel knackered, then as you carry on and your body gets used to working at that higher rate you ease into it. Sounds like you're doing a great job getting the weight down!

A friend and me played singles the other day,we usually play doubles but two guys could come this time so we decided to do singles,and a couple of days later confessed that he has not been so tired from a workout for very long.

The fun thing is that he is doing badmington and spinning a couple of times per week.

I however tried to do some running this summer,i could run like 500 meters then had to walk for a bit and so on,but i can play 2 hours of singles,sure i get tired if i meet someone that can make me run alot,but i make it...

The point is that your body can be different,my friend can do spinning for 1 hour nonstop with a trainer pushing the tempo,i would probably last tops 5 minutes if i held back hehe

I really have bad cardio but somehow tennis works better,maybe your body is more responding to normal cardio but is less adapted for short explosive starts and stops.
