Hi, I'm wondering I am 5'5 extremely leggy 7stone, and ride a 13.2hh welsh pony Also I know it's not the best photo. Here's another photo of me riding a 13hh Icelandic horse so yea.
Not at all too tall or heavy. You'd just get a different feeling riding bigger equines. I always say to look up photos/videos of William Fox-Pitt on his eventers whenever someone asks this question about height. You'll see what combination can work very well.
Am I the only one wondering how we got to this?
1. A nation of overweight, underworked horses and ponies.
2. A nation of people scared to work these horses and ponies in case they are 'too big'.
Sigh.
OP - you look fine, your saddle is fine, your pony is fine.
