Afternoon all, Hope your Sundays are going good. Speedy, Yuk - you have my sympathies, Jools - take it easy, I have had some minor probs with my calfs recently but nothing like what you seem to be suffering.
Lots of nice plodding going on today, 15 for me setting off at just before dawn - all done and dusted in just under 2 hrs to take me past 50 for the first time since March and first week of P&D D&D. Off to get some beers and put my feet up!!
TD - I guess all guides inc VDOT and all training programmes (Hadd, Daniels,P&D)are one hat fits all and not individual specific so not 100% but that's what I like about running, there's always options to suit you and your lifestyle. Glad the injections are working
Lawyeraaron - Have you looked at the mcmillan calculator? http://www.mcmillanrunning.com; My MLR, LSR and GA paces tend to hover around the same areas. If you feel the GA is too slow go for the 15% end, too fast aim for the 25% end.
Ken - +1 for eggynogs comments re more 20+ miles, I would extend your 19 and one other (at least ) out so you hit the last one 3 weeks out and feel confident.
