Do you ever turn back once you start your run?

This morning, I did an early run. I rolled out of bed, got dressed, checked the temperature, and headed out.

What I didn't check was the wind.

We have a chinook rolling in. (For those of you that don't live here, it means we get wind and warmer weather in the middle of winter. Chinooks can raise the temperature by 15-20 degrees.) The problem is, the warmer temperatures aren't here yet. The winds are.

What I figured would be a fairly comfortable -10c (14f) was instead a brutal, wind and snow in my face, type run. Really what I needed was another layer, but I didn't want to go back home to get it. I felt like if I went home, I wasn't sure I'd leave again. In fact, I was considering doing just that. Granted, I was contemplating going home and biking on my trainer, so it wouldn't be a complete loss. BUT, I need to run. I feel the difference when I skip runs, and I am training for a half marathon, which I'll be doing before any of my triathlons.

So, I toughed it out. I found out that the wind wasn't so bad when I was going in the other direction. My morning runs are on sidewalks, up and down streets, so I was never in the wind for too long at once (never out of it too long either). I considered it and decided that it wasn't a safety issue to keep going with the clothing I had on.

In the end, I finished my planned 6 km (3.7mi). When I got home, I checked the windchill, and it was -20c (-4f). Definitely a temperature I can run in, but another layer would have been appreciated.

I think I'm going to have to get over my desire not to have to go back home though. There are going to be times I forget things that I really need. In fact, having proper clothing is a very good reason to pop back into the house before carrying on.

I'm tough enough to run in -30c (-22f). That means I surely have enough mental strength to go back out of the house even though I went in.

What about you? Ever turn back? Do you go back out after?
