Woohoo! Good on you for pushing through and powering up the hill the second tie around.
.... and that's where the magic happens. Your mind is saying - it's time for a walk' and you say, 'not just yet' and you legs just keep on going. And you realise - i don't actually need to walk. I'm a lot stronger than I thought I was.
You're going to be stiff and sore in the morning though hehehehe
It is partly a mental thing, but I gritted my teeth. I ought to run tomorrow, but may not have time. Will make it up in the week.
You did well. ;-) The more you grit your teeth and push through the barriers the easier it gets to do it again and again.
But be careful..... down that road lies ultra marathons ;-)
