Got to disagree with you there! If it wasn't for the treadmill (creche included) I wouldn't be able to run at all for two weeks at a time.
I'm sorry but you're wrong.....I'M REALLY GLAD I GOT OFF MY ASS TO RUN ON THE TREADMILL....IT'S BETTER THAN NOT RUNNING AT ALL AND BEING A FAT ASS COUCH POT.....
(and as for carrying water? Yes it's a good idea to stay hydrated....I love to be able to sip on the stuff every 15 mins or so.....IT'S GOOD FOR YOU AND YOUR BODIES PERFORMANCE....)
So there!!!
