OK 20 miler done and dusted!
Radio 4 to listen to made it bearable and not dull at all.
I don't do intervals. I did try joining a running club but late nights at school made it tricky to get there on time.
Did a marathon last Jan - doing Goofy this year. Chose a slightly more advanced schedule (last year's LRs were 18) to help with the back to back.
Was feeling edgy as I feel I am slightly heavier this year and wondered what impact that might have. Judging by today - doesn't matter at all.
Good times!
Thanks for the input folks. Just gotta do it all again in a fortnight.
