the hill was tough, and yet there are reasons why it was so tough.

one – a dramatic change in our training weather – we have been training at 50 degrees, and Saturday was 80 degrees.

two – the hill is tough.

three – my brain is dead so I can’t think of any other reasons right now, but maybe you did not eat enough carbs, maybe not enough sleep? lots of reason, but it happens and it inset anything to worry about.
