running and not losing weight - even gaining...

Unfortunately upping your mileage makes you hungry, so it's pretty easy to accidentally eat more than you need when you're running a lot if you don't track carefully. It's very easy to think you're doing the same as ever but have your portions creep upwards.

Your muscles can also end up storing a bit more water etc. for repair when you're increasing exercise, and that can account for a pound or two with some people for sure.

I'm training for a half and have gained about that, maybe a bit more. My appetite really ramps up when my runs get over 10 miles. My runs burn between 700 and 1100 calories depending on intensity and length, but I can eat those back and more VERY easily.
Could also be water retention from sore muscles.

Guys could The increase of 1kg be in relation to building muscle mass if OP is adding a strength training session(s) or simply gaining muscle mass from running?

The first time I trained for a marathon I was surprised to find that I ended up gaining a few pounds. I wasn't logging or even paying attention to my calories at that time. I'm pretty certain I gained because I was burning a ton of calories in training AND then overeating to make up for it. Since then, I have logged my food during training and never had a problem. My weight stays right where I want it.

If you are tight with your logging, the weight gain can be due to a build up of fluid whilst you're increasing your mileage. THe fluid builds up around your joints to protect them whilst they're getting used to the extra impact. I find whenever I take a short break from running (about a week) after I've spent some increasing my distance, I automatically drop a kg or so over a few days.

Watching your calories is essential, but important to remember that muscle weighs more than fat. I am just as scale focused, but find that it helps my morale to try on a smaller size pair of jeans and feel how much looser it fits weekly. I did the dance of joy on the morning I could easily into a smaller size.

Run baby run! I ran competitively too, in the top 1% women runners in the nation in the 90s. Forget about the scale you're already skinny. Be sure you get the right calories and nutrition. Add upper body workouts for muscle tone, rowing or weight training is gr8 compliment. and be sure to stretch a lot in your lower body. Running builds great balanced muscles in your lower body and abs.

I have heard, and the is purely anecdotal, from people who were training for and then ran a marathon. Many did not lose anything through their training, and losses didn't start again until after the race. Tighten up your logging, that may help.

I have heard that too. I recently started upping my running distance a little and I got so hungry that I read up on it a bit. It seems to be pretty common to gain weight during race training if not really careful about logging. Most people just get super hungry from it. And you also want to feed your body well since it needs to recover, so you really have to be on point about your nutrition to get the best results.

Thank you so much for your replies. Yes, I do log, but I'm thinking I need to be much more vigilant. I ran a half a few years ago and lost quite a bit of weight, particularly as I upped the mileage. Perhaps my body is just getting used to running... I'm also thinking I need to add some weight training in as I'm worried that running will cause me to lose muscle?

I feel ya, lady. Ive been running for 7 years and, unfortunately, my body has adapted to running and it doesn't burn calories as much as it did when I first started running. The weight just fell off when I first started running! Now I've really plateaued and I know I gotta switch it up and "shock" my body. So Im incorporating two days of strength and I have switched one of my running days to a hill interval training day to hopefully build more strength and speed (: Good luck torsaer!

Give me an example of a distance of run, body weight, and amount of calories you logged for running. I will be able to tell you if you are accurate.

Also when I ran 6-18 miles everyday for 9 months straight, my weight would fluctuate 10lbs sometimes at 210lb body weight.

Recently I ran 6 miles in 55 minutes, runkeeper told me I'd burnt 619 calories. I'm 59 kg. and 160cm (5 ft 3)

Flat land you would of burned 500 calories. So as long as not extremely hilly, it is more than likely a slight over estimate.
