It should be possible to run it on the PC with 3GB, but the 2GB one might be cutting it a bit fine. It should be capable of running on both computers, frankly, but there are so many factors we can't know.
E.g. if you have other browser tabs running at the same time as the race which are consuming memory, maybe this will tip it over the edge and it won't run.
Set all plugins of the browser: ask to activate (firefox) un-tick always allowed to run (chrome)
It will make the browser use less memory than a browser that is always running plugins even when they are not in use.
@ Jack could you not make it so that it opens the race in the current window instead of it opening a new one?
Then at the end of the race, when you click continue it redirects you back to the home screen.
