Headline events including cycle fairs in Manchester, Bristol, Edinburgh and Glasgow take place this weekend, but organisers fear occasional and 'returning' cyclists will simply stay at home if downpours are forecast.
On Sunday, more than 100 'Pedalling Picnics' have been organised by volunteer rangers on the National Cycle Network. They are now anxious that their events, which are aimed to appeal to families and children in particular, will be a washout as a result of the rain that's driving in from the south-west.
Festival of Cycling co-ordinator Nick Harvey was today putting on a brave face and encouraging local event organisers not to be downhearted: "The British weather is fickle at the best of times and the Festival of Cycling, previously known as National Bike Week, has had more than its fair share of bad luck. But the rain seems to be blowing through faster than forecast and at least the temperature is rising!".
The Festival of Cycling comprises nearly 1,100 events taking place across the UK, including many on Bike2Work Day (20th June). Details of local events can be found at http://www.cyclingfestival.org.uk or by contacting local authorities, cycling clubs and campaign groups.
