Pete is walking 500,000 steps for the NHS

I am planning to walk 500,000 steps in May, all recorded on my pedometer!! I would like to raise a few quid for the NHS. My wife and I are both ex NHS staff nurses, and can only imagine what our ex colleagues have been going through. Not just the workload, but personal fear of the Covid 19 disease. I am not looking for fortunes, just loose change. Whatever amount is made by 31 May will go to the NHS. Thank you so much.
