What to Buy for a 100 Kilometer Race

A 100 kilometer race needs more than bib numbers and medals. You will need supplies for registration, course marking, aid stations, timing, medical support, volunteers, and the finish area. This shopping list helps you prepare those items before race week, when missing basics such as safety pins, cups, power banks, or route arrows are difficult to replace. Use the participant count and number of supply points to set quantities, then distribute everything by station before the course is opened.

Tips

Buy at least two safety pins per participant, plus a reserve of 10–15% for lost or damaged pins. Keep them at registration rather than packing them into race bags.
Plan reusable cups for every aid station, not only the finish area. As a starting point, prepare 3–4 cups per expected runner at each station and add extra if volunteers will also use them.
Prepare route arrows and kilometer markers before race week, including a reserve of about 10% for weather damage or misplaced signs. Pack them by course section so volunteers can set out one complete section at a time.
Give each timing, registration, and aid-station team a charged mobile phone and power bank. Charge all power banks the day before and pack extension cords and power strips where fixed power is available.
Separate bib numbers, wristbands, medals, and medal ribbons into labeled storage boxes before the event. Count medals against registered participants and keep at least 5% extra if late changes are possible.

Frequently asked questions

How many safety pins do I need for a 100 kilometer race?: Plan on two safety pins per participant, then add 10–15% spare pins. For 100 runners, that means 200 pins for normal use and roughly 20–30 additional pins.
How many cups are needed at a 100 kilometer race aid station?: Prepare about 3–4 reusable cups per expected runner at each aid station, adjusted for how many stations share the stock. For 100 runners, that is 300–400 cups per station before adding a small reserve.
When should I prepare the race bibs and participant wristbands?: Sort and label bib numbers and wristbands at least 2–3 days before race day. Keep them in separate storage boxes so registration volunteers can find each item without opening every box.
How many spare medals should I buy for a 100 kilometer race?: Buy one medal per expected finisher and add about 5% spare medals. For 100 expected finishers, prepare 105 medals so a damaged item or late finisher does not leave you short.
