Let's say that because you end your morning ride at work and you begin your afternoon ride from work, let's just call them commuting.

Just out of curiousity, if you "participate" in the commuting mileage thread, do you split the commuting/training portions of the distances or do you consider it all training or all commuting?

Ah, wait a sec, here's an option. Given that you commute to work and then go for a training ride, let's call that 2 rides with different purposes.
