Enjoy the replen SB. Good pace with your long uns and probably sensible this week to reign it in a bit from last weeks pace for now.
I hear good things about beetroot juice and know several competitive ultrarunners who swear by it. Maybe I'll try ths year, I was using chia seeds late last year, which have similar superfood qualities. Couldn't say I had noticable improvment from using, but at the time I was training a lot and running 50-60 mile ultras monthly on variable surfaces which make performances hard to compare. One thing I can probably say is as part of a quality diet generally it kept me unijured during my best and highest mileage running year yet - 2290 miles.
Good looking pace also there LS. Missed the GRJ program, but looking forward to some tourism up that way in the future, the rugged landscape up there is my favourite kind of backdrop and would be a new area forme to explore. Oh and enjoy "Getting yourself out there..."in 2013
Not many miles here as busy with youngun, But increased run frequency this week over last from 2 to 3 and will do some kind of short long run tomorrow hopefully. With less time there has been more emphasis on flatter and road surfaces so far, managing sub-8 pace regularly, faster than usual, but know I'm only about 75%, which is weird 
No road marathon planned for me (again), half consideing the new "Yorkshire Marathon" this October, but all 5000 places have filled less than 5 days! A guy I know from ultras and sometimes run with organises the Hardmoors trail ultra series and this year is also organising a 5 race series of trail mara/half/10k - starting Feb and then running about every 2 months through year, visiting lots of pretty and scenic areas of North York Moors and surrounding area. Also considering a hillier challenge in Lakes in June (will see how Isaac settles before I commit to training for that).
