Rasus y Bannau Checkpoint Guide
This blog provides details of the checkpoint locations, supplies, cut-off times, supporter / crew guidance and drop bag details for the 2026 Rasus y Bannau.

There are 9 checkpoints on the 100km race, 6 on the 75km Ultra Trail and 4 on the marathon. The race checkpoint location and distances are described below. The checkpoint locations can best be seen on the interactive maps available on the main event page.
Water will be provided at all checkpoints along with a mix of snacks. As is standard in Ultras and as per your compulsory kit there will not be any plastic cups for water or hot drinks. If you would like a hot drink you must have a suitable hard plastic cup and hot drinks will not be served into soft flasks or soft cups. Larger checkpoints will provide more substantial food, details of which can be found below.
There is a drop bag available for both ultra distance races. Details of which can be found at the bottom of the page.
Some of the checkpoints are remote with minimal parking or restricted access and therefore there are some points on the route and checkpoints which supporters or race crew are not allowed.

Drop Bags for the Ultra 100km and Ultra 75km
Both Ultra races have an an option of using a drop bag which will be taken to CP5 (33 miles) at Blaen Llia Forest car park. You will receive your drop bag at registration and you can only use this drop bag. Drop bags may get wet during transit, so if there is anything which you must keep dry it should be put in a waterproof plastic bag or drybag inside your drawstring drop bag.
The drop bags are pictured below and are the same standard issue drop bags that we have used at other events. You can re-use bags from previous races if it helps you to pack them before the event - just remember to clearly label them with your race number and drop bag number for the current race!
Drop bags will be handed to the race team outside the Theater. Bag drop will be open from 30 minutes before the race starts.
All drop bags will be returned to the event HQ in in Brecon and return can be expected from 1930 on the Saturday evening.
The images below show a fully packed drop bag (left picture) with the kit that was packed into it (right picture). The spare kit includes some size 9.5 HOKA Stinson trainers, a spare winter mid-layer, spare running leggings, spare t-shirt, spare socks, K-tape, lip balm, s-caps (electrolytes), body glide (lube), blister plasters, and some additional energy gels, drink powders and wine gums for the next section of the race. Of course it is up to you to decide what to pack in your drop bag.
