Why is it that whatever ones choice of aerobic exercise, sometimes it's a brutal slog, sometimes average and other times an unending delight where one could go on seemingly forever and unstoppable?

I've never been able to figure out a connection to any of those states with beforehand diet, sleep, stress, conditioning, mood, etc. — it remains a mystery to me.

Congratulations and good luck in the 10k.

I do know that when I least feel like going for a run, I get the most out of it. I love that feeling at the end when it seems that I can go on forever.

you mentioned and really getting in that zone. Obviously all that stuff is really important to your overall health and general athletic ability. But I've had those hard slogs on a good night's sleep and I have I had some incredibly euphoric runs after a night of shit sleep - and vice versa. And lots of those average ones.

And thanks for the wishes on the 10k!!

It sounds heavenly. Congratulations and keep up the good feeling.

Keep it up!

I try running again, or I’ll just hurt myself. Good job.

Three years ago after a twenty year lapse.

I wanna be running 25:21 5ks when I'm 68! I can't do it now, but I have 13 years to train.

Well done on your running success. It's really motivating to witness you challenging yourself and feeling the happiness of running. Good luck with your upcoming 10k race this autumn. Keep up the great effort!

Always jogged a 1 2 or 3 mile loop weekly since I was a teen. 55 years old too.

My longest run in the past was around 6 or 7 miles. Was hoping to do what you are now doing but the foot is crap now. Have gotten back to weights but no running...

Good luck with the 10k!!!! Maybe a half marathon after that? I can live vicariously.

I've never understood it...but I know a lot of people who love it.

Great accomplishment! Keep on!
