Too much?

[Daffy Dilly]

On the 28th I have an inhand show + gymkana up the road which I plan on going to. The day after (bank holiday) there is a trophy show.

Would it be too much for him to do both? Bearing in mind he isn't as fit as he should be, although he can comfortably do a 3/4 of an hour lesson mostly at trot and obviously it's broken up in the ring. I wouldn't do loads of classes at the trophy show, would enter on the day and see how he takes it.

if you dont go to hard on him in the gymkana then you should be alright. Inhand classes are not realy taxing on them.
I plan to do 3 ridden classes with stan on the 28th and one on the 29th but they are likely to be huge classes and stan is reasonably fit.
