Hopefully your ultra will be easier than mine. I know I wasn't ready five weeks later. I'll let you know if I'm ready after six weeks or not lol. Which are you racing?

I think you should be fine in 6 weeks. You'll have more confidence to run that marathon after our ultra :-)

This ^. Your confidence going into the marathon will be a lot higher knowing that you have already conquered distances greater than 26.2. If you can increase your mileage base before then and allow a good recovery after you finish the 50k, you should be perfectly fine after a few tune up runs.

I am trying to figure out what to run during those 6 weeks. Pick up the last 6 weeks of a marathon training plan or wing it? lol I am not good at winging it. I love to have a plan.

Post ultra - do a reverse taper, then a "forward" taper.

Ultra
W1 - 8
W2 - 13
W3 - 20

Marathon

Haha! That's exactly what I am doing right now! I ran my 50K July 26 and the marathon is next Sunday. However, you probably DON'T want to do it how I am doing it, ie: getting that silly concussion and missing pretty much the last month of marathon training. Sunday should be interesting!

Seriously, though, my plan up to that point was to follow HH Advanced I program. I took two days off...doing absolutely nothing and then picked up on the week where my long run was the 15 miler. I was just going to pick up where I left off. Unfortunately, I didn't get much further than that due to the head injury.

I agree with all of the above! Have fun!

{I think you'll be fine. If it's not a trail ultra, you won't be on your feet for too much longer than you would for a long run. You can just treat it like an extra long training run!}
