I have been working on my weight for just about a year. Started in May 2009 and have lost so far 145 pounds.
My method of exercise has been biking and the treadmill. Over the winter so far it's been just the treadmill. Basically everything has been going very smooth up till now.
I have been slowly increasing my running along the way, I started out walking at just 2.5 mph, and along the way worked up to jogging 6mph in two 40 minute sessions a day, six days a week.
I had been sustaining that schedule fine, 2 runs a day, 40 minutes with a 5 minute cooldown 6mph, all up till about 2 weeks ago. Basically I've hit an unexpected brick wall.
All of a sudden my legs are stiffening up bad, I had to scale back in speed to 5mph and I just struggle to make it. the first 2 days usually go great but by the third day my calves are tightening up and I'm getting cramps in them bad in the middle of the night. If I back off and sit around for a day or two I can get my wind back but not for long, not like before.
I'm not sure what to think, I haven't changed my diet, granted I eat very light probably 1500-1800 calories a day, It's what I've done all along. I'm at about 195 pounds right now and feel like I need to burn about another 20 - 30 pounds of fat off, so close to the finish but I am perplexed by this change.
I've read that lack of calcium and magnesium can be a source of bad cramping in the calf muscles, and have just started taking calcium and magnesium supplements today. After tonight's run I was just so burned I could barely finish.
Does anyone have any similar experiences or encounters with this?
(Edited) I forgot to add I do stretch before and after a run.
