Thanks shysal and nightowl for supportive comments. 
I have mixed feelings about 'other participants'! For a start most of them are likely to walk way past me in the first mile, esp if they have youth on their side!!--and whilst I'm happy to be at the back on my own, I am selfishly thinking I do need to keep my 'own pace' and don't want to be slowed down. Maybe I'm being too honest there, as I'm usually quite a supportive person. I just know I shall need to keep going.
But I'm sure you're right and everyone will be in encouraging mode--just like these wonderful Olympics.
I have found the way everyone unites to support all the participants, whichever country they're from, is almost as inspiring as the athletes themselves. I went to watch the diving last night, and walked a further 10 miles to add to the 20 the day before. Great fun--but my muscles did tell me they knew it, last night!
nightowl-- I was hoping I'd done my last long walk! But I see I shall have to fit in one more in 2 weeks time--probably wise, thank you.
Have a great weekend all you great WaM (inaday) forum members 
ps to add to the step discussion Frankel, Joanna Hall, who runs walking courses in London, reckons 52,400 steps for a marathon. I reckon I average 2100 steps a mile if my Fitbug is correct.
