Hi there, I'm a regular gym-goer who started running last week, using a 0 to 5k plan from a magazine. I'm not used to endurance so I knew I would find it tough but it's embarrassing that I'm tired after only two minutes of running. I'm currently doing walking/running intervals and am trying to focus on my technique and breathing but I felt like I was wasting my time today when my left ankle and all the way up the side of my lower leg hurt so much that I had to stop for a while. Already frustrated and disheartened! How do I deal with this??
