Cool, just sounded a tad worrying because you're increasing your daily milage by 300% with no recovery time. I do think motivation can let you do that, but maybe for 3-4 days until your body reacts. Just be cautious. Are you running morning, lunch, evening now?
Did finally manage to put some money in a few weeks ago, it's a great cause you're doing it for. Have some close friends with massive mental health problems and there is not very much help out there for them. Mind do a great job, well in for supporting them.
