O woe is me! To start with 90 seconds is definitely more than 30 seconds extra to last week. It was wearisome to say the least. At times I felt as though I was running on the spot. I'm sure I'll never get to W3. It took 40 minutes before I was breathing normally again after I finished the "run" and before I got home from the park in the car I had turned from very hot into chilled. It wasn't nice.
Then if all that wasn't enough notpheidippides said I'm running flat footed and should be landing on ball of foot at least. I can't see me changing now after 66 years! Perhaps that was why my family always laughed at me when I was a child.
