That Hurt a Little Bit

Decided on a speed session today and I picked one I wasn't sure I could complete - I did but not without a smidgen of 'cheating'. I pushed it harder than I have for a long time and found myself struggling to keep on the treadmill - hence the slight cheating but better than than not complete. Despite it hurting, it felt good. To know I pushed out of my comfort zone. Going forward I'm going to keep pushing myself. I can see it's got to hurt if there's going to be a gain. Definitely going to repeat today's session and hopefully there'll be a little less cheating the next time....
