Grey Percheron Mare offered for share

I would like to share my Grey Percheron Mare. She is 16.1hh, 15years old. She used to be used as a carriage horse for weddings but now I just use her for the odd hack, about once or twice a week. She would love some more exercise and for someone to take her out in a carriage. She will be based with me near uppingham, Rutland. If there is anyone who is interested in riding and helping with her care please email me at alcj13@yahoo.com She is very kind natured and calm but not boring. Can I make it quite clear though that she is up for Share not a loan or sale. Thanks.
