I am pretty overweight. I can run up to about 10km, and my heart/breathing is fine, it's just my legs that start to give up. I've gone for three runs in the last 8 days, longest being 4.7km which I was pretty sore after. The other two were 3.7 and 3.8. I felt much better after those.
Running
A place for runners.
For racing, half's are my favorite, despite not racing them often. Long enough to be hard, long enough to not be a pain cave race, but don't destroy you for weeks to recover.
For a day to day run, 8 miles/12km is a good sweet spot for me. A good duration, but not too long, not much recovery needed. Can just go do it.
9-13 mile (20k) weekend run around a beautiful lake.
10 miles.
It’s long enough to be worth going. It’s enough distance to hold a warm-up, cool down, and whatever kind of tempo, fartleks, hills, or whatnot you’d like to toss in the middle. If you’re just taking it easy around town you can see some stuff. And I get done before I get bored.
I enjoy running on my lunch break at work, so a shorter run is good for me. I'll run 2 miles most days but every few runs I'll run 5km, just to see if I'm improving.
My average mile time for a 5k. Is like 9 minutes a mile right now, so I'm not an advanced runner by any means.
Probably the 10k. It's a nice round number and also the first distance I ran in a race (except for races as a kid). I think it's also the distance that suits me the best.
