Note: I'm not hosting this marathon, but I'm here to spread news.

Sonic Speed is a planned marathon that will be showcasing various speedruns from many Sonic games. It will be starting sometime in February 2016, raising money for Child's Play @ http://childsplaycharity.org/ .

The two main organizers are Paulie9990 and LittleBigness who can both be found at their respective Twitch channels.

The marathon is invite-only, meaning that you can only run a game at the marathon if you are approached by one of the two organizers. However, you could still contact them if you do feel that there may be some needed change.

You can find the marathon's Twitch channel at http://www.twitch.tv/sonicspeedmarathon and more information on the marathon here: https://goo.gl/BlATzm
