I'm just beginning running, or rather run-walking with the target of running all 5k of the Flora Light next Sunday.
At first everything was fine, but once I hit running for 5 minutes, I have started feeling sick and faint and have to stop. I made myself run 5k on the treadmill OK, but every time I run outside I get this problem.
Am I being a big wuss? Should I just try and push through it, or does anyone have any ideas why this happens?
