I think you really have to not worry about what other people are thinking/doing. Last year with run/walk in the last few miles of every race I did I overtook people that were much younger and fitter looking than me! for me that was brilliant
Ecky - you will definitely get there - remember most of it is in your head, definitely with longer distances
I really couldn't face going out in the horrible bitter cold wind today, and yesterday I spent 5 hours on my bike so wasn't really sure what my legs could handle, so I went to the gym to the treadmill. Had forgotten how boring and how hot it is - only managed about 5 miles, but better than nothing!
ooh Franny - back to Lisbon!! Wish I could join you...
