Those running the 8k might want to work together. Jake, Jason, Philippe and Steve, not sure what your goals are? I assume Jake and Jason are planning 25:20ish and maybe Philippe, too. Steve might be high 26 or low 27.
For all of you, I suggest shooting for negative splits to finish strong and if anything, catch and pass others. maybe run, just below full throttle for 4 miles and then at the last mile, throw everything you have into it. I know Jason and Jake train together so maybe you two can hang on the heels of Bert Rodriguez and allow him to pull you along or vice versa. You probably do not want him to get too far away though, as he has a great kick.
Melissa, there are few top flight Ethiopians running it on the women's side as is Alisa Harvey. At 41 or so, she is several age groups removed from her prime and you should be in the running for 1st place.
Matt Ernst, not sure what your goal is time wise?
