I really like running to help me lose weight! Do you like running?
If by running you mean the method of terrestrial locomotion, then definitely! I was out for a jog today! Have you ever done a race? 
Of course that's what I mean! And no, I haven't. Have you?
Yep! I've done a bunch. While the term running can actually mean anything from jogging to sprinting. I mostly do long distance races. I highly recommend it!
That sounds really nice! Ever ran any marathons?
Yes I have ran on before, and I'm currently training for another one right now! It's a 42.195 km race. Pretty intense!
Damn that's way more than I've ever tried! 
Running is probably the worlds most accessible sport. You don't need much to do it. Just start slow and be patient, it doesn't take long to build up the distance with consistancy.
