Kerry.. it's not because they are busy by any chance?. There will be runners who have lost property, not got their kit bag back at the finish, not got their name in the results because their chip malfunctioned, results queries etc etc. And you are pestering them about a vaguely possible way of getting an entry in some future year. Hardly a priority for them right this minute. Give them a break for a bit and try another day. Best of luck BTW.
