Has anyone ever been diagnosed with this? I am about 12kg overweight…semi regular runner. Have ramped up on intensity the last month after a particular unhealthy holiday in order to try and lose weight and get fit. I’ve gone from three runs a week to one interval run, one threshold run and one long run but covering maybe 10% more distance than normal. Have also started a beginners introductory weights video 3 x a week using very light weights (each session is about 30mins). I have one complete rest day a week. Doesn’t sound too much right? Plus been eating healthier (cut out wine, cakes, chocolate). Have lost about 3kg over four weeks (Yahy!) and look better…felt amazing for the first two weeks but now my sleeping is all over the place…wake up super early, don’t ever feel well rested, mildly agitated for the last 2 weeks. What’s going on? I should be feeling amazing and sleeping like a baby?! I’ve wondered if it might be overtraining syndrome - too much too soon? But it doesn’t FEEL too much? I’m enjoying every workout? Anyone experienced similar? I’m reluctant to cut down on training and step back…but I feel rubbish.
