Pesach Marathon

So there's an article about a rabbi running the Boston marathon on during Pesach and having to carbo-load on matza and potatoes. When I reached this line, I did a double take:

The level of observance varies. An Orthodox Jew, for instance, does not work or drive on the first two and the last two days of Passover, so he or she would not run a marathon on those days.

It's not an issue for Pesner, whose liberal Reform branch generally suggests followers hold a seder on just the first day of the holiday, though the dietary rules are observed the entire week.

What? This guy is Reform? And what branch of Reform recommends observing dietary rules during all of Pesach?
