Fundraising 750 bucks in 9 weeks?

[irishtwins1112]

I am training for a half marathon the weekend of October 4th(Jacksonville Marine Corps Half Marathon). I just noticed on the run Disney site that the Tower of Terror Ten Miler still has registrations through Noah's Light Foundation. The fundraising goal is 750 bucks. I haven't done fundraising in probably 20 years. How realistic would it be to raise that much in 9 weeks? I was thinking I might ditch the half and go for the ten miler.
