Kirsty met with the dedicated fundraisers of Kidney Wales who are celebrating their 50th anniversary by undertaking a walk around Wales.
They started out this morning from Llandrindod Hospital and were finishing the day in Brecon.
Kirsty also took the opportunity to visit the dialysis unit at the hospital. The unit has proved life changing for so many constituents, who no longer have to travel so far to get this essential treatment.
Due to the new investment in the hospital the unit is to be extended.
