Eat first thing, then take a shower with anti-bacterial soap, so you won't stink (I use Dial AB). Have your stuff ready the night before (clothes, etc.), so you are not fudging around with that. Leave at daylight, so motorists see you. I used to like to ride in the dark, but dark is scary, and no witnesses to a hit-and-run. Motorists should see you, and know they will be seen by others, so they can't get away with road-rage in the dark.

I ride 10 miles each way; it takes 45 minutes. If I leave at 6am, I still get there 2 hours before most people show up. If I leave at 7am, I am still there by 8am.

Wear a reflective vest, stand out, be noticed.
