Catch - your digital swim coach - is the Official Training Partner for Great North Swim. Here’s your guide to training, kit, fuelling & race day.
By Rebecca Wetten, Co-Founder & Head Coach at Catch
The 500m is a brilliant first open water challenge - fun, friendly & achievable for anyone who can swim a few lengths of front crawl.
Set on the stunning Lake Windermere, the Great North Swim is the UK’s biggest open water event - part race, part festival, all about community. Thousands of swimmers take part across six distances, from 250m to 10k, cheered on by crowds, music & lakeside buzz.
The Half mile is the perfect introduction to open water swimming. The course is well-marked, the safety cover is excellent & the atmosphere is unbeatable. It’s the perfect mix of excitement, challenge & pure enjoyment.
We’ll be there too - come find us at the Catch stand for a chat or a few last-minute tips.
If you can already swim 50m of front crawl, you’re ready to start building up your font crawl technique & fitness. The key is building confidence & comfort in the water, rather than worrying about speed.
Start with short, regular swims - even 15-20 minutes at a time adds up. As you feel stronger, extend the distance gradually. Two to three swims a week is ideal.
Small tweaks to your technique will make a bigger difference than fitness. Concentrate on:
- Head & body position: keep your head low, body flat & hips high.
- Breathing: breathe often & calmly, breathing out bubbles when your face is in the water.
Catch’s weekly video lessons break these skills - & lots more - into simple steps to help you build smoother, more confident front crawl.

Before race day, try at least one swim outdoors - a lake, river or the sea. It helps you get used to the temperature, & swimming without walls to push off.
Practise:
- Sighting: look ahead every now & again to see where you’re going.
- Breathing rhythm: stay calm if there’s a bit of chop.
- Confidence: try to feel relaxed while swimming in open water.
A few open water sessions will make race day feel more familiar instead of daunting.
Give yourself three ways to win, such as:
- Bronze: finish feeling calm & proud.
- Silver: complete it mostly front crawl.
- Gold: feel smooth, strong & ready for more distance next time.

You won’t need to eat or drink during a half mile swim, but being fuelled & hydrated beforehand makes all the difference.
Sip water or an electrolyte drink the night before & again a few hours before your swim.
Have a light, familiar breakfast like porridge, toast or a banana. Nothing new or too heavy on race morning.
Make sure they are comfortable, & new-ish - it’ll help you see where you’re going. Anti-fog before you start - baby shampoo or saliva works well.
Wetsuits are optional above 15°C, & they give warmth & buoyancy. If you prefer to swim skins (no wetsuit), you’ll need a tow float. For wetsuit tips, read Catch’s wetsuit guide.
A neoprene cap or vest can add warmth without much drag. Gloves & booties will feel toasty, but are a bit heavier.
Keep training light in the final week. Focus on gentle swims, stretching & staying relaxed. Get good sleep, eat well & trust your preparation.
-Pack your kit early
- Sip electrolytes
- Eat familiar food
- Check the course map
- Stay relaxed
- Warm up in the water to settle your breathing
- Don’t sprint the first 100m
- Sight every 6-10 strokes
- Find your rhythm & enjoy it
If you start to panic during your swim, calm your breathing, float for a moment, then start again slowly. You’ll soon find your groove.
You did it - half a mile in open water!
- Warm up: get dry & dressed quickly.
- Refuel: grab a snack & a hot drink.
- Reflect: celebrate what went well.
- Plan ahead: maybe the 1-mile next year?
