Wow I can't believe I did that!! I actually ran!! for 20 minutes!! without stopping!! I'm over-exclaiming now!!
And whilst contemplating the world out my garage window for 20 minutes (I was on the treadmill), I came to the conclusion that I actually prefer running on the treadmill to outside! I never thought I would say that, but I just did. Treadmilling eliminated all that bumpy uneven ground, there were no kerbs to trip on and thankfully no dog poo.
I also noticed that coming up to 8 minutes into the run, my legs suddenly felt all "light" and it was remarkably easy after that - is that how long it takes for those endorphins to kick in??
Had to work today so didn't have time to weigh and measure, but so what, there's always next week.
I've also found that my best time of day for running is first thing in the morning - empty bladder, empty stomach definitely suits me better. Just a quick rinse with mouthwash!! Best reward for getting up at 6.30am? - sitting down with a nice bowl of soggy muesli!
Good luck with your runs, folks.
