Last Sunday I tried to find my marathon pace and my heart rate strap didn't work (https://www.strava.com/activities/12920436090).
Today, again, my heart rate strap didn't work so I removed it and relied on the heart rate measured by my watch.
The problem was today was windy. Very, very windy. Gusty winds that didn't follow any pattern. Sometimes tail wind, very often cross winds and, what felt most of the time, head winds.
That means that last Sunday's heart rate was useless and today's pace was useless.
So, I have decide I'm going to pace my Valencia marathon based on heart rate. I'm going to aim to run it at 145 - 155 bpm. That is between 85% and 90% of my maximal heart rate (170bpm).
I don't know what pace that would be. My best guess is somewhere between 5m15" (a 3:41:31 marathon) and 4m45" (a 3:20:26 marathon).
Finishing is a must. Finishing in that bracket would be an amazing result and I'd be satisfied with how the whole year went.
But now that I have put concrete figures to it you can bet I'll aim for the lower one.
One week to find out. Uncomfortably excited about it.
