is 2.75 miles in 21 minutes 31 seconds a good time for someone reasonable new to runnig to be getting?
will i just improve by keep runnig, and increasing speed, etc? i found that taking deep breaths, and holding for a few seconds before runnig decreases the chances of getting a stitch, has anyone else tried this, or know why it works? is it because it stretches the diaphragm?
