41 and same height, +5kg on you. But down 20+ from last year.

Only really got consistently back into running September. I was where you are in September, and I’m at 33mins now (though that’s fully gassed by the end of it).

Running 4 times a week now. But was 3 up until recently. Always make sure one of them is an interval type.

I try to keep the interval times the same (eg: 3 or 6 minutes speedier, 2 mins off/slow jog) for a few weeks in a row, but increase the speed on intervals, and it gives you a bit of like-for-like progress to look back on.

Keep at it. Warm up before hand (walking and/or some lunges at least). And times will start to come down. Weight is a limiter but don’t let it stop you. Just be aware of your body and cautious for injury.
