The BUTM is scheduled for 22nd and 23rd February, 2025.

Registration and payment is via Racematix. You will be transferred to the Racematix registration page when proceeding to entry at the bottom of this page. If you already have a profile with Racematix, you can log in to your profile to enter. If you do not have a profile on Racematix, you will need to first establish your profile with relevant details. This is free and an easy process that takes a few minutes. Accurate personal details per passport/IC must be entered to avoid any confusion during registration and race pack collection. The personal information is also used for registration of points for the various circuits (such as the Malaysian Ultra League Championship) and/or for qualifying points for other races (e.g. ITRA). BUT does not release personal information to any third parties except name and date of birth together with results to ITRA and UTMB for points collection.

Once logged into your Racematix account, you can then select the race category and any add-ons (optional bus transfers and optional late pickup of Race Pack - see below) before proceeding to payment. There are two payment options provided in Racematix:

1) Via direct transfer to the BUT bank account (details provided below).
2) Payment via Paypal / Credit Card, which incurs bank charges.

Please note that there are admin fees associated with Paypal and Credit Card. If you pay with Paypal or Credit Card, your confirmation will be immediate upon payment. If you pay via bank transfer or transfer with for instance Wise to the bank account, you will need to return to the Racematix registration page to upload a copy of the payment confirmation. This will then be verified, and your registration confirmed within a 7-day period. When using bank transfer or bank-in, please make clear reference to event and name of runner, e.g. "BUTM 50k John Doe". This will ensure easy identification of you as the payee and ensure you get registered without any glitches. We do (unfortunately) still receive payments without any reference on a regular basis, and this makes it difficult to identify the payee and confirm the correct runner.

If you should have any questions or problems with the registration and payment, please email to This email address is being protected from spambots. You need JavaScript enabled to view it. or contact +60 10 933 4800 for assistance

For participants who cannot make it for the race pack collection within the allocated times, a "late pickup" option for Race Pack collection at the start venue on the morning of the race is available for a fee - please refer to details under the "Itinerary" page. During the race registration process on Racematix, you will be prompted to choose the "standard" or the "late" Race Pack collection - please make sure that you are fully aware of what these options involve.

Entitlements 

Prizes for the men and women "Overall" category (which includes all age groups) will be provided for the 100, 50 and 30k categories and include merchandize from sponsors and own products. No prizes are awarded in the short (5-10 km) course except special prizes for the youth category as this is mainly intended as a non-competitive family run.

The regular entry fee includes the following entitlements:

• Borneo Ultra Trail Marathon Event tee
• Race bib
• Timing chip and timing during event
• Water and aid at all water stations
• Fruits, meals, snacks at selected aid stations on the course
• A meal at the finish line for the 100k, 50k and 30k categories and at the halfway station for the 100k 
• Medical backup and support during the event
• Basic accident insurance during the event only (please note this has nominal coverage only, and we encourage participants to ensure they are sufficiently covered)
• Logistical support for transfers of DNF during race

Finishers of the race (having completed the full course within the set time limits) further receive:

• Finisher's medal.
• All finishers will be able to download their official e-cert stating their official time and standing in the event.
• 100 km, 50 km and 30 km categories will receive a finisher's tee
• ITRA points and UTMB qualification points will be awarded to competitors who complete the 30k, 50k or 100k courses within the stipulated cutoff times.  

A sizing table for event and finisher shirts is included below and on the Racematix system. Please ensure that you study this to get the correct size. Ladies should be aware that the unisex sizes are larger than the women's cuts, so please take note. 

The correct T-shirt size must be chosen when registering for the event via Racematix. Please note that it will be the specific shirt size for the event that will count, not the "preferred" size in your general Racematix profile. So if you wish to change T-shirt size, you need to log into your event registration and change it there. It is not sufficient to change it in your Racematix profile. If you prefer to exchange the T-shirts for a Food Aid donation, please refer to the description below.

   

Say No Thanks to T-shirt in exchange for Food Aid Donation

If your closet is already full of race shirts that you hardly use we are happy to offer you the option of saying "No Thanks" to shirts from the BUTM and exchange this for a food aid donation to the less fortunate and needy in the race area. We are already working with a local entity as part of our Corporate Social and Environmental Responsibility (CSER) programme for donations, and this will ensure that the entire amount saved on shirts will go directly to the recipients as food aid donations.

If you want to take this option, please select the "No Thanks - Donate" option under the T-shirt "Size" option in Racematix. Please note that your selection at the time of close of registrations will be final and that saying No Thanks to T-shirts is for both the event and the finisher T-shirt for the categories that include a finisher shirt. 

Merchandise 

We have additional T-shirts and a head-gear design on offer. These need to be pre-ordered and paid via Racematix and will be handed out during Racepack Collection. The two T-shirt options (blue and grey) and the head-gear depicted below will be available for order on Racematix during registration. If you already registered and want to add one or more of these items, you may go to Racematix, re-open your registration, add the item(s) and then pay through one of the payment options via bank transfer or Paypal. Sale of Merchandise will end together with the close of registrations as we need to place the order to receive it in time for the event. The T-shirt sizing follows the same sizing chart as the event and finisher shirts provided above.

 

Transfers, Cancellation & Refunds

The following refund rules apply for BUTM 2025.

The general refund policy is:

• Payments are non-refundable.
• Runners may request a bib swap or transfer before closure of normal registrations with an admin fee of RM30 per request. 
• Change of category is possible for a fee of RM30 only until close of entries. 

Please take note of the deadline for bib swap or change of category to avoid disappointment. All T-shirts and Medals are ordered on close of normal entries, and we are therefore not able to accommodate further requests. 

Should Borneo Ultra Trails be forced to postpone or cancel the event, participants will be given a choice between deferring their registration (if the event is postponed) or receive a refund minus a 10% administration fee.
