Gain weight after running?

hjsportsed1

I am a new runner. This past weekend, I ran/walked 3.7 miles and I gained two pounds. I assume this is muscles retaining water for repair? My running program said I burned like 700+ calories so I was a bit confused.

Totally water retention. My scale weight is 2 pounds higher the morning after I run. It comes off in 3-4 days.

i don't know that a 3.7 mile walk-run could burn 700 calories.

the weight blip could be water, but it could be natural up and downs we have day to day, week to week. for how long and how often do you weigh yourself?

was that your first walk-run? or are you in the middle of a program such as a c25k?

It's water retention. But are you sure about that calorie burn? You would have to weigh 300 lbs to burn 700 calories running 3.7 miles.

Any new exercise regime has a good potential for creating soreness/inflammation and therefore causing water retention and temporary weight gain out of line with calorie balance. Give it, and yourself, some time.

PS - if you weigh 300lbs and ran the whole 3.7 miles your net calories would be about 700. Walking is approx half the calories per mile compared to running.

I weigh 203. The program, Runtastic, is what spit out the 700 calories.

Not my first walk/run. Last weekend, I did my first 5K, but had been doing C25K training for three weeks before that.

Big over-estimate then, maybe the app assumed it was all running and gross, not net, calories.
Maybe they just choose an exaggerated algorithm deliberately (not unusual sadly).

Personally I would use these common formulae:
Net Running calories Spent = (Body weight in pounds) x (0.63) x (Distance in miles)
Net Walking calories Spent = (Body weight in pounds) x (0.30) x (Distance in miles)

Half run / half walk would be roughly.....

Run 237 + Walk 113 = 350cals
