That’s what the training appears to mostly be about: Getting your body used to moving when your legs are already tired.
I am at the highest mileage week of the training plan that calls for fifty miles, culminating with a 22 miler on already tired legs.
I’m not really looking forward to it but hopefully it will pass easily enough.
I’ve run the last three days in a row with distances of 10.5, 6 and another 6. I even cycled to work a couple of times just to add to the muscle confusion and tiredness.
I’ve been stocking up on carbs and protein today to help with muscle recovery and energy reserves for tomorrow.
