Remember when you ran for 1 whole kilometre?!!! Without stopping?!!!
Remember your first 5k? I do. I had to have a 2 hour sleep and take two aspirins!
Remember the first time you went for your first 60 minute run?!!!
You ran for A WHOLE HOUR!!!!
We forget. Those distances and times were a big deal.
They still are.
Just running is a big deal.
Give yourself some credit.
