Mistakes...

Made a big mistake last friday, the day i did the 1 hour run.
Firstly, i got a new pair of socks, it was a Adidas, much more thin than the usuall socks i wear. This caused my shoes to be slighty loose, and this thin socks didn't have any paddings such as the older socks. This cause slight pain as i ran, it was just a slight pain, so i just ignored and ran...
Secondly, 15 minutes before the 1hour mark, i did a 5 minute dash, it was at speed 10.5.
Because of these 2, today, i couldn't even run for 10 minutes, both my calves and left foot was aching badly. Was feeling fine the whole weekend, but few minutes on the treadmill and i knew what i had done wrong.
So lesson learnt... never wear anything new that u aren't used to, and never try to push too hard when u arent ready for it.
