Overview
The Lakes in a Day Half has been designed to be the perfect challenge for those building up to the full Lakes in a Day, training for a first ultra, or simply seeking a challenging trail run. Explore the undulating hills of the southern end of the Lake District, offering a stunning yet achievable adventure for all levels of trail runners.
Journey from the bustling Lake District Town of Ambleside to the quieter village of Cartmel. All the fun of the longer distance event but on a fully waymarked route. Follow the western shoreline of Lake Windermere, taking in Claiffe Heights and Bigland Tarn.
Waymarking
The route is waymarked with yellow arrows on a black background from Ambleside to Cartmel, however you will be given a map to carry in case it is needed. GPS units may be used as back up, in conjunction with your map.
- Bring your own cup
- Plastic bottle free
- Sustainability policy
This event is trying to raise its sustainability game. Yes, it's small stuff, but it's a start, and every bit helps. There are two main changes:
Cups
Feed station cups are this event's biggest source of waste so it is completely stopping the use of them. There will be no cups at feed stations. You will need to bring your own hydration system, whether this is a camel back, hydration vest, soft bottle or simply bring your own collapsible cup, carry this with you and it can be topped up at the feed stations.
T-shirts
Many of you love and use them, however, some of them get disposed of without ever getting used. So, when you enter you will have the option to choose "No T-Shirt". The cost of your entry will remain the same, and the equivalent of the cost of your T-Shirt will be donated to the selected charity.

Recce days
There will be seven recce days over the coming months, each recce day is guided by a member of the NAV4 Team who have endless experience of skills and safety. The team are happy to impart their knowledge along with hints and tips on how to best cover each section of the event route. These days are an excellent opportunity to get to know the route, get hints on the best line for you and to brush up on your navigation skills. This is also the perfect opportunity to try out your kit, figure out what you need, how you will carry it and when to use/not use the items you have with you.
There are also two skills based sessions, one offering a half day on Hallsfell Ridge for those nervous of the terrain and the other is ‘LiAD Skills on The Dodds’ with an enhanced navigational and hillskills input.
