Is this an aggresive marathon plan ?

Too risky, too aggressive.

You're currently at ~15 miles a week, long run of 8, and want to make an immediate jump to 12? Then add two miles to that long run each week? If you would be following the rule of your long run being no more than 50% of your weekly mileage, you'd have weekly increases of 60%. 17% and 14% just over the first three weeks.

To further your self-examining question, not jut "WHY?", but "Why so soon?" Plenty of marathons out there, dozens every weekend from October through April. Pick one in the spring and use the winter to build your running base.

IMO, too risky...

If you want to do a "solid" event this year, why not a half marathon, or a fast 5 or 10k?  In order to hit your Oct 25 marathon, you are building very quickly, especially coming off your current run volume.

I would skip the marathon and focus on another distance.  If you want a marathon, why not a winter/spring marathon when you would have time to build properly for it?

ummmm ... how do i say this without losing all face ... I AGREE

after today's run of a 12 miler , it seemed obvious that i could pronbably do it but the going wd be way hard and probably risky too . esp. given that i can't manage more than 2 weekday runs at the most !

I was thnking that i could push it and even the numbers wouldn't compute on the increease of the long run with the weekly mileage , was hoping that the long run increments were conservative enough (10% over prev. week) to be managed .

one would think with my learning over the last couple years , i'd have learnt enuff to not be so optimistic in my planning but clearly ... need to keep my ambition in check with my training

but thanks a ton for the accurate feedback ...
