I am not going to give you some long analysis, someone else will. But based on your training speeds, I say yes. Your last tempo run was right at 3:20 marathon pace so your legs know what that speed fills like. If you train smart this should be easily doable.

I agree with Viich. What is your age? Can you manage 150+ miles a month? On your log 75 miles is the most you have logged in a month. I see an injury in your future. Use the 10% rule and go from there. .Ha, I could be wrong!

I would say it might be a bit of a reach. Right now, looking at your log, most of your runs (even your tempo runs) are in the low to mid-8:00mpm pace. You do have one tempo run at 7:39 but that is just one run and my guess would be that you pushed it a little harder than you would be able to do for 26.2 miles. Though you really dont have any long runs out there. After you have done a few longer runs (at least over 10 miles, but probably closer to 13 or 14 miles) see what pace you had for those and how they felt. If they felt easy, then they are probably at your marathon pace because the second half always gets harder. If you struggled holding that pace, then slow it down a bit. I would just start running more in preparation (dump the speed stuff) for the marathon and see how it goes. You will have a better feel for your long run pace after you have done this for a while.

Need more info about you. Age. Gender. Marathon experience. Running experience. Injuries. How did that marathon feel? Did you jog it or run it? You want to knock off 40 minutes. That's a lot. You've only done 200 miles this year. You may need more of a base to see some improvement. And base is mileage and long runs. Worry about that first, then speed.

Male. 40 yrs old. 1 race in my entire life and that was the marathon last fall. been running for 2 years now. Had reconstructive knee surgery 22 years ago last week (repaired ACL, LCL & PCL on left knee by Dr. Shelburn in Indy). Run it...jog it? I don't know. I started running, but finished jogging. If you'll note my training log, this week and last week I have been lax. I do have a life other than running and life keeps getting in the way of running. We have a 64 mile bike ride tomorrow so I'm not gonna do my speed work tonight as my schedule says. I'll start building on miles. I'm gonna sign up for a 5K to be run on 5/24 just to see what I can do.

Hmmm. You may have your work cut out. It's good you bike, that helps w/ overall fitness, but they don't equal one another. You'll have to seriously evaluate how you felt after your first marathon - ie, how much was left in the tank, what could you have done had you trained properly, etc. I mean, if you trained a bit or fairly well and said, WTF, I'll do a marathon, then you may be able to close the gap with some serious sticktuitiveness. If you trained well and gave it your all, well, that's something else. I have a life outside of running, too, but if you want to set up kick-ass goals, then you gotta follow through. For me, it's meant a reduction in boozin' and fly fishing. You must become running's bitch. I had a strong return-to-running marathon in the fall with pretty decent training, then set up a goal of cutting 12ish minutes for a spring marathon. I cut about 5ish minutes and I had trained for the second one SO much more. Of course, it was a tougher marathon and I got up the marathon day just feeling I wasn't going to have an A game. But still, it was a lot of time to cut. I still say, give it your all, but be careful to avoid injury. Listen to your body - while I stand by my statement about becoming running's bitch, you don't wanna become a schedule slave. (I saw you mentioned schedule.) Good luck.

I'd say no, not on that base. 10 mpw is what a lot of beginners are running, and beginning runners usually don't attempt marathons. It doesn't matter that you're likely faster than a lot of beginners, your overall fitness just isn't there at this point. Get that up a bit and then tackle another marathon.
