A couple of thoughts learned on this forum might be relevant now.
I think it was the much-missed Tim who wrote that we should not regard running as a penance eg “I must run off that huge Christmas dinner I ate”. Running should be an enjoyment, not self-flagellation.
Another helpful expression is “You can’t outrun the knife and fork”. Lots of writers ask about running and losing weight. Well, it only takes a bit of maths to realise that reducing calories in is more effective than burning calories off, unless you’re an Olympic athlete.
My Garmin watch reckons I expend 100 kcal per km.
So combining the two pieces of advice above, I reckon my run yesterday burned off just two mince pies!!! But I don’t regret eating them. 🤣
