Hey Reece. I was in your position some time ago, not too sure about how good my bike is to tackle downhill, or even XC for that matter. My first ride in epping forest 2 years ago went great and it performed exactly as I had hoped for. I had a Muddyfox sport full suss. Recently upgrading with a new frame and parts got me going to go even faster and set a demanding pace with my bike downhill. However, the point behind this is I don't own an expensive bike. Its a 6 year old marin, heavy and durable. All within student budget and mainly entry level parts (deore gearing, fox rear shock, old bombers, old mono M4s etc.). It's not the bike, it's the rider. I can vouch for that.
A pitch is a good ride. You'll be fine mate
