I hear ya. Training regularly comes easy - it's the getting started which is really difficult.

For me, I break it down into tiny steps. Teeny tiny steps. If I'm even thinking of going for a run, I'll put on my running tights. No pressure to run, just wearing the tights. Then I'll change into my run bra & vest. Still no pressure, I'm not going for run, I'm just wearing comfy clothes. Then I'll put my trainers on.

Then I'll go outside. Maybe I'll walk to the corner of the street. Well. I'm outside now. I could run to the next junction. I'm halfway to the nice river path, it'd be nice to see the ducklings. Oh I'm at the river, a few minutes along the river will be nice. Oh I've ran 1.5miles already, I might as well head back home now and that's a 3 mile run done for the day.

Basically, I try not to think of it as one huge task - running. Instead, lots of little things, there's no pressure at each juncture to continue if I really really can't.. but I usually find that I can. And once I'm out, it's easier to keep going.

And hey, if I don't make it far/out the door, at least I tried. I didn't sit on the couch moaning about the fact I should go for a run. I at least took steps towards it, and next time I can try to go that one bit further.
