The Great North Run will be hit by rain and strong gusts of wind today as stormy conditions roll in across much of the UK, heralding the beginning of autumn.
As some 55,000 people set off on the half-marathon in Newcastle, winds in the area are expected to be up to 40mph, and will increase to 45mph in the afternoon.
Western areas of Scotland are expected to see the worst rain of the day, with 30-40mm falling in some places. It will also bear the brunt of the windy conditions, with Northern Ireland and Cumbria, with some tree branches expected to be brought down by the gusts.
The rest of the UK is expected to see cool, cloudy and windy conditions, with no signs of a return of any sunshine.
