I've done enough of these to know you have to do them for your own reasons. This past weekend I completed 3 marathons. A personal goal important only to me. I plan on being there Sunday. Very few people will know me, there will be no family members cheering me on, and I doubt seriously that I will be competitive in my AG. Never the less I plan on supporting the Striders and running my 10th LFM. Were I in your shoes and at peace with my decision I would run, but keep it low key. If you have a great day there's plenty of time to “talk the talk” after the finish line. If you don't you can always say you came to celebrate the 30th and honor the past.
