Thanks Peter. I haven't booked any races yet, but I'll probably go for a 10k or two in July-Sept, and a half marathon later in the year. My plan is to work more on speed during the summer, while keeping up a reasonable level of endurance. How about you - are you back to regular training/racing?
Madbee - if the HM is 3 weeks before your marathon, why not run it as part of a longer training run and add another seven miles, either before or after? If you are intending to do a run exceeding 20 miles (I did 21m this year, and 22m last year), then I would do it this week to ensure that there is enough recovery. TBH I think the extra couple of miles is more psychologically beneficial rather than physical.
GK - LOL @ your son shouting out, very similar to my son this morning. Brilliant enthusiasm.
