Drop Bag for 104km Participants
During race pack collection, 104km participants will receive one white bag with your BIB number clearly written on it for their drop bag intended for Checkpoint D.
Before the race start, you must deposit your designated cpC drop bag in the marked “drop bag cpC” area at the starting point, near the finisher arch.
These drop bags will be available at cpD from 10:00 AM onwards and will be transported back to the race venue after 11:30 PM on Saturday.
You are responsible for collecting your drop bag from the venue by 10:00 AM on Sunday. Any uncollected bags after this time may be disposed of or reused by the organizers. If you withdraw (DNF) at cpD, you will be able to retrieve your drop bag there.
Please be aware that the race organizers are not responsible for any loss or damage to the contents of your drop bag. We strongly advise against placing valuable items in these bags.
Remember that there is specific mandatory equipment required for the entire course (including a headlamp, jacket, whistle, phone with a Taiwan operator SIM card, space blanket, etc.).
What to consider including in your drop bag? The section ahead involves a significant 1500m of vertical ascent, and you will be heading into the night, where temperatures may drop:
- Extra food
- Spare socks or shoes
- Extra clothing layers
- Extra batteries or a spare headlamp (a good headlamp is mandatory at the start, and carrying two light sources is mandatory after leaving cpC1!!)
- We advise against placing trekking poles in your drop bag due to the risk of accidental damage.
- Anti-chafing cream, tape, etc.

We are pleased to inform you that the 2025 Formosa Trail 104km has been selected as a qualifying race for the 2027 Western States 100. Runners who complete the race within 28 hours will qualify to enter a lottery where the runners for Western States will be selected.

Official Course Markings
The official Formosa Trail course will be marked with BEAST RED/WHITE or ORANGE ribbons featuring REFLECTIVE stripes. Please note that other ribbons you may encounter are not official Formosa Trail markings, though they might help you stay on a general trail.
In addition to ribbons, we will use supplementary signage at important intersections (e.g., Intersection X, Y, Z or significant turns). At these points, you must navigate independently.
It is mandatory to have a GPS device with the course installed and to know how to use it.
There are numerous reflective TAGs along the course, visible with a headlamp. These TAGs are primarily placed leading to cpA1 and from 大尖山 Dajian Mountain to the finish line.
