Sorry...I'm being lazy and cutting and pasting this from the Mileage thread

. But I wanted to add my training in here. I am by NO MEANS an expert Cecilia..but thought I'd jump in here and post what I'm doing. Believe me when I tell you I go back and forth between confidence and outright terror! I know what my body can and cannot handle...and having run the marathon injured last year...I knew that was something I wanted to avoid at all costs.
Not sure why on earth I decided to the Goofy thing

. Just a glutton for punishment. That and I have a very persuasive running partner...thanks Scott! Anyway...here's my plan. I know it's way light on miles...but I'm happy to report that I feel strong and I'm pleased with my pace.
Here's what it should have looked like if I stuck totally to the plan we developed. Every other week was pull back so I could allow my muscles to heal and prevent injury. Unfortunately LTO and between illness, Pilates certifiation and weather that has been... I didn't actually hit the totals as listed on a few weeks..."best laid plans" as they say! WTS This is close to accurate...I didn't go back and actually add up the miles (being totally lazy). Also..keep in mind that my sat half distance is actually a walk/run combo...I plan to just totally take it easy for the half . Aiming for a slow and easy half and hopefully a decent full of under 5 hours (goal is 4:30). Here it is starting 10 weeks into training or so...when the miles began to ramp up. I came in with a weak base due to the injury...
25/20/28/20/31/20/34/20/37/let the taper begin
I know this is less than impressive mileage

BUT...I do supplement with cardio XT twice a week (biking, ski machine, elliptical, etc). I also do approx. 6 days a week of Pilates. So I'm feeling like I"m in the best shape of my life. MPM has been solid and I'm pretty much on target for an ok marathon time if the stars align. BIG FAT "IF" . And that's knowing that survival is ultimate goal that weekend LOL!
Happy training my fellow

people!
Sooo...after a boring and long winded post my non-experienced answer to your question is that your mileage is impressive...your training is stellar and I think you are going to be fine without the B2B. Stick with what has been working for you...you'll do awesome C.
