Presumably you're an accomplished horse-person ? It does look great fun, but also hellish difficult to avoid keeling over 
as long as the groom leans round the corners its ok
I'm Fairly accomplished, I work for an equestrian magazine, there is me in an office full of women..anything remotly risky they get me to do it...scurry driving jousting, galloping along the edge of cliffs, roughing it in Transylvania etc etc
