Has anyone done this? For someone who manages a step count of over 10,000 steps a day through work, is it doable or am I still going to find it tough? My job involves lots of walking up and down stairs and admittedly my hips and knees hurt at the end of the day 😂 really want to give this a go and I will be doing it for charity, but if I'm going to really suffer I might do a bake off instead 🤣
