Greg hope you all the best ankles brake are not very good.
I had a plate in my ankle for a couple of year so know what you'll being go through.
Once the casts off you will need some physiotherapy as the plate is screwed on the bone the soft tissue around it will be sore.
Riding a bike will help but your leg will feel rought sometime.
One thing which you can think lucky is has it's winter you wouldn't be bocking too much anyway.
With luck in three months you'll be back to your old self.
Hope to see you in London and take care of yourself.
They never show me my plate but I could feel it under the skin !
Now I can see it ..... Don't panic they had to remove my plate ( I broke it ).
Here my plate
