I did my first podcast of Week 1 today. I found it very hard, especially on my lungs. I also felt quite sore in my calf muscles as I was doing it.
I did 5 / 8 run sections (though more of a jog), and feel really proud of myself. I felt really good at the end of the session. I'm going to have a rest day or two, then try again on Sunday. I reckon it'll take me a few extra goes to complet podcast fully 3 times, but I'm really excited. Good luck to everybody doing their sessions today
