Running more than 800 km

I hit the 800 km mark running yesterday.Not many people in the world have done this. It is impossible for me to google it to check if there is someone that have done more than 800 km run giving people advise. No running 800 km for dummies book out there. So every step is an unknown land now. How do injuries that happen after 800 km look like? No idea. Nobody knows. I feel good. No injuries and still have energy for more. The weather forecast for the week is good so I look forward to it
