I've raised £300 to Helipads for Hospitals

I am raising money for Helipads for Hospitals as part of my D of E Bronze Award. I am aiming to cycle the distance of Lands End to John O'Groats (837 miles) over the next 3 months. I am also asking for you to save your aluminium cans (drinks cans) to donate to this charity.
Big Red Bins are placed in public places to help collect these cans - it costs £600 for each of these - I am hoping to raise at least half of this initially and if possible, the full amount!

Helipads For Hospitals is a UK charity founded by former RAF and Air Ambulance helicopter pilot John Nowell.
The aim is to collect about one million drinks cans and other unwanted aluminium items (i. e. saucepans) and to use the raw material to form an alloy strong enough to build a helipad on site at hospitals.
Even when traffic is light, and drivers are considerate, this added distance can add minutes to a journey when speed is vital.
So, by recycling aluminium, H4H will reduce the need to mine bauxite for aluminium. It takes 20 times as much energy to make an aluminium can as it does to recycle one, so we will save energy. By picking up litter, including cans, we are helping to save our environment, too.
