I think from my point of view it’s getting an understanding of how all of my runners react differently to certain stresses on the body and I’m starting to learn with yourself we need to be a little bit more cautious. With that in mind just being selective with your races will be important as you don’t want to effect your training too often. But you did the right thing here and based on what you have said I would definitely sit out Sunday or run it easy (if you need it for your 8 races). At this stage of the plan there’s no point pushing too hard. I do tend to try and stick to the plan as much as possible too, but again perhaps I needed to be more reactive to Sundays run which ended up being a PB when were anticipating a more steady sub 1:30. It’s always a tricky one and sometimes a really thin line as you’ve seen this week and hence why the feedback is crucial. So to summarize. My advice would be run easy Sunday or rest. And be selective with your race entries. Bear in mind the last few weeks you’ve run the hardest marathon in the UK and a half marathon PB, there’s a little inevitability about a niggle right now given that schedule. Equally I perhaps should have reacted again with the plan but just hate putting easy runs in there all the time. I’ll drop you a message as well.
