>General Running>Will I be ready?
Roads were made for journeys...
That'd be, in my opinion, not enough to *race* on... but you could probably jog through it (perhaps with some nice walk breaks) and still have a good time. It just depends on what your goals are.
Generally I stay far, far away from threads like this one as well as the prevalent--I have x, y, z symptoms and I'm scheduled to visit with an orthopedist in 2 weeks, should I still run my half marathon, please help??!!-- because the answer is highly personal and depends on many factors including the runner's experience level, pain threshold and competitive temperament. But I agree 100% with wingz here. No chance will you be ready to race 9.3 miles in 6 weeks, but you could easily be ready to run it at an easy pace, treating it as your long run for that week.
Regarding the 10% "rule", here' s my take from personal experience. Long term, there is no way you can continually increase by 10% every week and not break down. If I were to do that, I'd be running 90 miles a week in just 6 weeks and then 3 weeks later I'd be running nearly 120 miles a week. I would break. No question. However, short term, you can increase much more than 10% per week, especially--and this is the key--if you are returning to a level you've previously handled well. When I started training again last summer, I went from zero to 50 miles per week in about 7 weeks. Obviously I had to break the 10% rule a few times to get there, but then I leveled off in the 50 range for weeks and months on end (hell I'm still there) while my body adjusted to that workload and just let the miles do their work. My weekly % increases during that build up were 177%, 42%, 10%, 20%, 8%, 7%, 24%.
