Wear the right clothing

Choose thin layers of loose-fitting clothing in lighter colours to help you stay cool. It’s also a good idea to choose clothes made from moisture wicking fabric. This draws sweat away from the body to the outer surface of the material, where it can dry quickly and easily.

Still too hot? Why not try an ice vest for the ultimate chilled experience! These lightweight vests include pockets with special cooling packs to keep you comfortable when the temperatures rise.

Keep hydrated

We sweat more when cycling in hot weather, so staying hydrated is key. Try not to wait until you feel thirsty to drink water – instead, take small sips frequently throughout the day. You could also freeze bottles of water the night before to enjoy ice cold refreshment throughout your ride!

Children dehydrate faster than adults and may not remember to pause to drink. Keep water bottles within easy reach and set reminders every 10-15 minutes for everyone to take a sip.

Consider the time of day

Check the weather forecast before setting off and try to avoid the hottest part of the day – this is usually between 11am and 3pm. Before 10am and after 6pm are good choices; temperatures and humidity levels tend to be lower so you can enjoy a more comfortable ride.

Stay safe in the sun 

Sun protection is important all year round, but especially during the summer when UV rays are stronger. Apply a high factor suncream (NHS advice recommends factor 30 or above) 15 to 30 minutes before exposure. Reapply to any exposed areas every two hours, or more frequently if you’ve been sweating a lot.

You can add extra protection by wearing suitable clothing, such as a wide brimmed hat or cap, sunglasses, and light-weight trousers or long-sleeve tops.

Take it easy

Our bodies have to work harder in the heat, so don’t be afraid to ease off and take things slow. This could include stopping for frequent breaks, planning a shorter cycle than usual, or choosing a route that doesn’t go uphill!

When to postpone a ride

It’s important to listen to your body and consider how you feel before setting off. If you’re feeling tired, lightheaded or generally a bit ‘off’ then it’s usually best to cycle another time if it’s very hot outside. Taking a day off is much better than overdoing it or getting sunburnt.

However, the British summer can be very unpredictable, so check out our tips for cycling whatever the weather!
