In reply to TheDrunkenBakers:
Cool, makes sense. She does 10k in about 60mins whereas I'm going for sub 48 mins this time on the Saturday. Doing the 'recovery' run, as you put it sounds like fun and will be a real test of my current decent form (three previous 10ks in under 50 and two longer well paced runs of 14 and 17km).
And no stitch for a while too, which is a bonus, although I put this down to loads of painkillers before a run.
