Still in no-woman's land with the Hood to Coast, but I'm not freaking out about the unknown. I'm going to plan on the marathon and if the relay pops up, we'll see...
That 3:40 has been on my mind a lot. Like, is that even remotely feasible? That's a pretty big chunk (4 minutes) off my PR. So, last night I used McMillan Running Calculator to see what it would predict for me. This site takes your race time for any race and then predicts what you can reasonably expect to run at other distances - assuming quality training.
The predicted time for my marathon, based on my 1:44:19 was EXACTLY 3:40:00.
