It's been noted in several posts over at Runners World.com that ALOT of women GAIN weight while training for a marathon. This is with all the miles they run in addition to watching what they eat. I am currently training for a few marathons this year and desperately need to lose 20 lbs (10 I've always had, another 10 since starting a fulltime job and being surrounded by office treats!)I'm starting to get concerned that the training will take me in the opposite direction of my goals! can someone explain to me why this might happen? Various theories were brought up but the 2 main ones were cortisol (from stress from the training) and too FEW calories. I'm still also trying to strike the perfect balance between Cathe videos and my running. It would probably help if I cut the running to 3 days per week instead of 4-5 but I'm afraid I won't be prepared for my races. Any thoughts on this?
