I'm struggling to break 30 hours a month atm - if I ran my commute maybe that would help, but so often I need the car at work in case I end up having to stay late and I don't feel the run home at the end of the day (happening more and more often...).
However, the vast majority of my training is running - mainly flat and road in the week (boo) with off-road and Orienteering at the weekend. I'd want to do more intervaly-type stuff but don't really have the motivation on my own, similar to driving out to the moors to put in some hilly runs post-work - I really should man up! However, what with it being so flat here, most runs are at a decent clip, although often too short. I'm still relying on the base-work I put in during a good October-December - I never seem to be able to carry it through past February though, so have a few 'fallow' months (OK, getting back into racing months) before a resurgence in the summer. At least I hope that happens again this year!
