Does commuting count as training?

To anyone who rides back to SE London there's a loop around Rotherhithe (turn left at the Rotherhithe tunnel roundabout, on the Thames side) that - buses apart - gives you about 4 mins of even-paced riding - 8 mins if you use the roundabout at the surrey quays end.

Thanks for this, I've just been looking on google, when you say that you spin at the Surrey Quays end, do you mean the roundabout where Redcliff rd meets Surrey Quays rd?

What kind of training / intervals do you manage to get in? I fancy giving this a go either v early morning or after work.
