Likewise, I do most my running about 30-40s/km slower than what I reckon my MP would be, and would possibly be even slower if I was targeting a marathon and doing longer mileage?
But like GB says, I have recently been doing more of my longer runs at mostly easy pace but trying to build down to a quick few km.
It’s my half this weekend. If it goes well I’ll probably target a half ironman 12 weeks later, but a first standalone Mara is tempting…
