Morning Crun, welcome to the forum. You'll find out we're a friendly lot, although many of us are raving mad...
Any questions you have, just ask - although you may find the answers in previous threads.
Well done on the 1.5 miles, a solution I use for stitch is: don't eat immediately before you go running. If you do get stitch, breathe in, through your mouth, slowly, then exhale, through your mouth again, quickly/suddenly if you know what I mean. Also try running with your hands above your head for a minute or so. Although you will look like a berk, and cars will honk at you as they pass, if it gets rid of the stitch, who cares lol?!
