the marriage and relationship were doomed from the start. NEXT
This is the dumbest question ever, but I'll pretend it's real for a sec. The day (and marriage) isn't all about you, but it's also not all about her. You wouldn't and shouldn't be married to someone who doesn't accept that you're a serious runner or support your goals like running the Olympic Trials. At the same time.
Bring her with you. Run the race Saturday morning.Take her out Saturday night.
