The world's biggest road race gets under way this Sunday, and Met Office forecasters are predicting that it could be one of the hottest days of the year so far.
Conditions will favour spectators rather than the runners, with some sunshine and very warm conditions with the chance of a shower during the race. Highs of around 20 °C are expected for the afternoon.
The Met Office is working closely with the organisers and emergency services, including the London Ambulance Service, to ensure they are prepared for the conditions.
Elsewhere in the country temperatures will be well above average, reaching the mid to high teens in many places. There will be a fair amount of cloud around with some showers.
