Quechua is camping stuff by the looks of it, so you might find it a bit warm for trekking around a golf course in? But they have gear for running on Decathlon as well which will probably be fine.
I had a New Balance water resistant jacket I bought from TK Maxx, but to be honest I always got a bit warm and sweaty when I had it in, as I guess it wasn't very breathable as not designed for sport as such. Now I have an Under Armour golf one (found cheap on ebay) and I've only worn it once but I could feel the difference, kept the rain off without making me too hot. So while you don't need golf gear as such, it's worth getting something designed for sport at least.
