Not going to lie, getting out of my warm bed at 6am this morning took some doing. It was pretty darn cold out there with frost everywhere! The run felt a bit tough, but I think my legs were still feeling it from last night's spinning class.
Thanks to all for the suggestions on the running belt, I ended up buying one on Amazon and today was my first time using it. It was so comfortable that I forgot I had it on me and had a momentary panic when I walked in the door and suddenly thought 'Oh no! Where's my phone!'. So that's a good result!
