Hip/leg pain 1 week from marathon help!

If your logs are near-accurate, my main advice is next time you decide to do a marathon don't do long runs so far out of your "comfort" zone (and generally run more).  You've been playing injury roulette so it's not too surprising that something went wrong.

Only advice I can offer now is to rest it.  Probably not what you want to hear with your marathon planned for Sunday.  Good luck.

Where in your hip does it hurt? I only ask cuz I started having some issues that sound similar, at least from the vague description of "my hip hurts" - cuz that's all I could really say at first. Depending on where it hurts, some stretching/foam roller action might help. I had some pain sort of in my butt too - since then, I've done a lot of the "pigeon" pose, which is a yoga pose (google it), as well as various other glute stretches - that got it pretty well. The one where you lay on your back, bring your opposite knee in and cross the leg that hurts over the other leg to stretch those muscles was great too.

Get thee to a Rolfer or active-release therapist early this week; otherwise, rest, stretch, massage, and ice.

Oh, and if the pain is like it was on your last run, you might want to consider pulling out of the mary early...26.2 miles can really exacerbate an injury and could have you on the sidelines much longer than you'd like.

Hopefully, it's something that just a little TLC will help.

Could be ITB, could be high hamstring strain or pull, could be any number of issues.

If it's a strain/pull, rest is about the best you can do right now.

The vast majority never think they are training too hard or too fast.

I'm just going by your logs, but I see weekly mileage (and long run) of:
8 (3)
16 (7)
16 (6)
3 (3)
27 (9)
30 (16)
10 (5)
20 (13)
16 (15)
30 (10)
31 (18)
22 (9)
21 (9)
36 (22)
15 (6)

That's simply a relatively high risk running pattern (i.e., pushing volume and long run distance without an established base).  For someone with years of running prior to this, they might get away with that no problem.  For somebody getting ready for their first marathon, they're probably betting against the house.

I understand i haven't trained for this marathon the "standard" way.  And i've had a lot of races in there thats why my mileage hasn't been consistant.  I have been a runner for 8 years so i have a good base.  I just haven't ever done a marathon. 

The thing is i did a 18 mile run the day after a tough off road duathlon.  I did the 22 mile run 1.5 weeks ago.  And i ran last week after the 22 mile run and i was fine.  I was a little tired, but nothing hurt for any of my runs after the 22 miler except for a week after.  I honestly think i did something that day on my bike or that evening when i was playing golf.  I don't think it had to do with my running. 

Anyway i know my mileage is low thats why i'm being conservative on my pace.  Thanks for all the suggestions.  I actually feel much better today after a lot of TP ball therapy and icing.  Hopefully it doesn't hit me at mile 10 and i can't finish.

Quite possible.  But I'll bet with the house and only suggest you at least consider it in future training.  Regardless, best of luck!
