That largely depends on the size and profile of your event.
Most organisers don't care who you're sponsored by or who's logo you wear.
What event are you taking part in?
Companies, more specifically the people that own them, are either predisposed to giving money to local charities or they're not. They would be more likely to give you sponsorship if the charity is local and the event is local. If it's televised too, excellent, even local news paper coverage is good.
