A bit harsh on yourself to go with “complete write off”. I’d only use that if you missed every run. You’ve just done a marathon. Granted it sucked, but you did it. I’m sure there would have been a time in your life where the thought of running a marathon would be madness. But I agree, time to reset a little and hopefully find some solutions going forward. Nice Work seem to be pretty good these days at deferring races, so if you don’t feel ready I would recommend that. I’m looking like I might have to do the same as I’m still fucked from my marathon 🤦‍♂️ Try not to be too hard on yourself though cos running the ultras and marathons you have is still pretty bad ass!!
