As a slight diversion to the running your are doing Malcs (and everyone else, you seem to be inspiring people to join in. Myself included did a nice 4.25 in 35:42 which for a man built for comfort like me is quite good), I'm going to ask some really important questions.
1. Favourite Film? 2. Roast Chicken or Roast Beef? 3. Favorite Christmas Song? 4. Road Bike or Mountain Bike? 5. Garmin or App on Phone? and 6. Apart from when traning is it acceptable to wear white socks in public?
I like the idea of a run on Christmas day but Mrs Reg may take something very valuable off me an serve instead of Pigs in Blankets. And by the time i've watched Elf, Muppets Christmas Carol and the Queen, I'm done.
I'm liking the training plan and have already got a couple of sessions in mind to adapt. 4M with 2M at marathon pace is on for tomorrow.
Christmas Day: Wake up, Open Presents, Wed 5M steady (approx 8:30 miles in 42 mins), Eat, Drink and be very merry!
Boxing Day: Wake Up, take some ibruprofen, drink some rehydration fluid, go back to bed, wake up again, eat a bacon sandwich, Thu 5M of 1M jog, then 3M at half-marathon pace (22 mins) then 1M jog, Eat Drink and be very merry again.
