Incredible speed runs streaming thanks to Summer Games Done Quick 2015 - watch now

Summer Games Done Quick 2015 is underway, and has already provided both thrills and heart-warming feelings.

Games Done Quick is a speed-running marathon in which top gamers perform incredible feats of skill and agility in the hope of raising money for charity. By coughing up funds, viewers can challenge participants to particularly difficult or entertaining endeavours.

As usual, gamers have responded with generosity. At time of writing, the summer marathon had already pulled in $76,748.33, which is awesome. All donations are sent directly to Doctors Without Borders (Médecins Sans Frontières), a humanitarian aid organisation assisting those most in need of medical care.

We've popped the Twitch embed above so you can check out the action, which runs right through to August 1. The full schedule has something for every type of gamer.

The brainchild of the Speed Demos Archive team, Games Done Quick has become one of the most popular regular charity events games culture has ever produced.

To learn more and make a donation, visit the GDQ website. If you haven't got any change to hand over, you can help raise awareness just by watching and sharing.
