I was commuting 18.7 each way, and doing it two days a week. Then I moved 30 miles away, and got a great idea from other posters here: I drive in Monday morning with the bike in the car. Then I bike home Monday night, get up and bike in Tuesday morning, and drive home Tuesday night. Repeat for Wednesday and Thursday. It was a beautiful plan and I tried it for my first time yesterday. I was 25.5 miles into the ride, only 4 miles from home, when a Lexus hit me from behind. I'm going to compose a nice long post now and tell all about it. But I still think the arrangement was a good idea - I'm just going to need a week or so to recover. Nothing broken, just a lot of bad bruises.
