Wondering what to do tomorrow? Do you have a bike? Then get involved in the Innertube Postcode Challenge.

Here is what it is all about according to the Innertube website – where they now have an interactive ma!

Event – The Innertube Map Postcode Challenge

Explore and discover the off-street traffic-free cycle routes of North Edinburgh by taking the Innertube map Postcode Challenge on Sunday 12th June!

Here’s how to take part:

1. Get onto the North Edinburgh cycle network wherever you like and is most convenient – look at the Innertube Map to find your nearest entrance. You can start anywhere on the red, brown, blue, yellow and purple lines.

2. Track down one of the ten stands. They are spaced out around the network and you won’t have to go far to find the first one. The stands are being run by various Edinburgh organisations, including Edinburgh and Lothian Greenspace Trust, Sustrans, Changeworks, and the People’s Postcode Lottery.

3. They will give you a participant’s card with space for ten postcodes and stamp it with your first postcode to prove you have visited them (they may also give you a little prize of their own). There’s no need to register – just turn up and ask for a card. There’s one card per team, but don’t worry, there are plenty of prizes.

4. Go on to the next stand and have your card stamped again. Each stand will be able to give you a clue where to go next, but all the locations will be on the network shown on the Innertube map, and you’ll never need to go on a road whilst taking part. And you can’t get lost.

5. When you have been to all ten locations, and collected your ten postcodes, take your completed card to the main desk at Fiveways Junction by 4pm to see what you have won. You won’t know what prize, or how many, until you hand your card in. As well as prizes to win on the day, everyone gets to enter a free draw to win bigger prizes.

So basically, spend the afternoon on your bike and win prizes!

Taking part is totally free, and is supported by the People’s Postcode Lottery as part of the Bike Station and Edinburgh and Lothian Greenspace Trust’s project to promote Edinburgh’s off-street cycling and walking network through the Innertube map.
