Got in two ten minute miles on the treadmill - the person before me had left it set at interval, so I thought "why not?", and did intervals rotating between zero incline and 3 incline, 2 minutes each. This was a new challenge for me, I tend to see if I can go faster instead of harder, so it felt good to keep that up for 20 minutes. I had to stop after 20 minutes because it was time for my awesome Thursday class. Some parts were challenging, some weren't - I think I'm going to up my weights for that class.
Ready for anything!
