we played Keyhole and then we decided that we would try to to Relay. It actually went way better than we expected. We started with doing it first at a trot but then we realised that it was going well so we added a little more speed. I also did my first canter with Kaïja without holding her mane and I can say that my seat and balance has improuved a lot since when we started cantering back in October. Here is a video of Keyhole and a video of Relay were you can see the exchange.
