Oh No! Hope you heal quickly. The training will happen. The upcoming races you have may be a bit slower than you hoped, but you still have tons of time for Star Wars and PHM. And plenty of time to get a 10k still
For POT a USATF certified race is the gold standard. However, I and others have reported using non-certified races to get a POT. I was injured last year and finding a certified race in the 2 weeks between when I was cleared to run again and the deadline when POT was due was tough because I had family commitments on those weekends as well. What you want to be sure is that the race you are looking at a has an
official timekeeping system, and that
they post results online. Once you are done and the results are posted you go to the runDisney website and enter your information including a link to the official results.
What do you consider around Boston? Within an hour of the city? The website
http://runningintheusa.com is where I find my races. You click on a map to indicate the state or states you are interested in, then I select 10k specifically to narrow it down. I'm in Worcester County and I can find a 10k at least 3x a month from now until November that would be within a reasonable driving distance for me. Depending where you live, southern NH, RI or other surrounding states also make it fairly easy to find something that will work. One caveat, try to do some research on the races you are considering before you sign up to see how the course compares to your training. I did a 10k in Bedford Ma at the VA hospital around veterans day, and the course was super hilly, and I run on hills all the time. I had looked at the course profile and thought it looked similar to the hills I train on, but when I got home and looked at the Garmin data I had climbed twice the elevation as normal!
