Riding a horse through Mongolia

Hello! I'm planning to travel to Mongolia with a friend of mine in September. The current plan is to buy horses there, travel through the steppes for about 3 weeks, and then head back home. Since we'd like to have a slightly larger group (ideally around 4 people) for this crazy trip, we're looking for people who would also like to do something like this. The plan might sound a bit crazy, but we are both quite experienced when it comes to such trips and are determined to do it. More about us: we are both from Poland, I've been living in Germany for a few years and work as a doctor, my friend works as a physiotherapist and still lives in Poland. Together we've already done, for example, a bike trip around Crimea, and we are both around 33 years old. We like to laugh and love spending our free time doing any kind of sport. Since we don't want to travel completely blind, anyone who is interested, we'd like to meet in person to get to know each other and also do some sports (including riding) together. We want to make sure we can stand each other for 3 weeks 😉. I can provide more details if you're interested. Many things still need to be arranged, and we are also very flexible. The only thing that unfortunately cannot be changed is the month we want to travel (it's about weather conditions, among other things). I'll be very happy to hear from anyone interested!
