This was considerably easier than last week's 30 miler, and that felt easy. Rather than letting my pace fall in to a more natural rhythm down the hills I changed my foot plant and shortened my stride and held way back. Not sure, but I think today had considerably more elevation gain and I also ran 2 laps on Walker Ranch (2400+ of gain just on Walker's 15 miles), the ice and mud made it more interesting. I made a couple changes to my caloric intake also, no Gatorade, just water + 9g of CHO every 30:00. One liter of half water/ V8 juice before starting. This was my typical 'breakfast' before Ironman and it suits me well.
