Ok, so the flying thing OR becoming a grandmother (for the first or ANY other time) are certainly excuses I can respect.
And yes, I did know you were older than me, but I suspect you are in the range of my oldest sibling (I'm the last of a large family). In any event, you are an inspiration for me to keep at it - I like "knowing" people older than me who do multiple races in one weekend It can be my goal in 9 years for my 60th (but probably without a marathon, I just don't have any interest in a full marathon).
Not that I'm one to disclose on a public forum my age, but I ran the SW Dark Side on my birthday...my 64th birthday. And next year if I do something stupid, face planting and breaking my right arm, I'll be covered under Medicare!
Best of all, my annoying older brother will be 70 in a few years. Yes, boys and girls, sibling rivalry survives in your 60s and beyond!
Yeah, I don't have it in me for a full marathon...my feet wouldn't make it.
