So... I have always had problems with stitches when running - even if I was breathing right or in shape, then here I was reccomended to drink loads .. and it worked! Until today, w5r3: 20 straight minutes. I must admit I hadn't drank much in the morning, but still... Do you reckon it's all about the drinking? I have a lot of breath,I do 40 minutes of spinning 3 times a week.
