Tips for runner events are here.
We start with 10 Flight Stamps and need 5 Flight Stamps per flight. We can collect up to 180 Flight Stamps by doing tasks that change every 8 hours. That will be 190 without quest and dragon tv.

The gridcoin rewards will turn to mazecoins when the grid ends. So you should decide what you want/need more before starting runs.
A hint : If you have a dragon rescue that will finish soon, don't do a run. If a rescue finishes while you are doing a run, it will crash your run and you will loose it.
