A friend told me to add 15 minutes on to a flat marathon time to give a realistic snod time does this sound about right?
I have averaged 55 miles a week this year but since May only once ran over 18 miles lots of runs in the 13-16 mile range. I am running a 20 mile race on Sunday then 5 weeks to go to snod- would you try to get in a couple of 20+ runs in the last 5 weeks?
Got a 20 mile race Sunday morning will give me an indication on my form for Snowdon- lots of miles recently but mostly fell and trail so not sure where I am for a road marathon. Also only one run over 20 miles since May!
