Sources & method: Sprint and long hurdle specifications follow World Athletics (WA) Technical Rules, USATF Rules of Competition, and World Masters Athletics (WMA) 2025 Competition Rules. Hurdle positions are computed as: Hn = distance-to-H1 + (n−1) × between-hurdle-spacing. Training (jammed/bunched) spacing recommendations follow published coaching methodology.

Why Hurdle Specs Differ by Age Group
Hurdle height and spacing are adjusted to match the biomechanical capacity and stride length of each age group. A regulation 42-inch (106.7 cm) hurdle at 9.14 m spacing designed for elite male sprinters would be impossible — and dangerous — for an 11-year-old or a 70-year-old. The governing bodies (World Athletics, USATF, WMA) have set progressive specifications so athletes at every stage compete and train safely without sacrificing technique.
For masters athletes, both the height and the race distance decrease with age. A 65-year-old man might contest 80 m hurdles at 76.2 cm instead of the open 110 m at 106.7 cm — but the technical requirement (clearing without loss of forward momentum) is just as demanding relative to his sprint speed.
Reading the Hurdle Position Table
The "distance from start" column shows exactly where to place each hurdle stake on the track surface. To set up a race or training session:
- Measure from the start line (or appropriate stagger mark for 400m events) with a steel tape.
- H1 = distance-to-first-hurdle; H2 = H1 + spacing; H3 = H2 + spacing … and so on.
- The total of H_n + run-in to finish should equal the race distance. Use the calculator's built-in verification shown under each event.
- On most tracks, permanent coloured marks are painted at hurdle positions for the major events (yellow for 100/110m sprint hurdles, green for 400m/300m). This calculator helps when you need a non-standard age-group layout on a general-purpose track.
Training Spacing (Jammed and Bunched Hurdling)
When introducing athletes to hurdles, experienced coaches reduce the inter-hurdle spacing to develop rhythm before advancing to race distance. The tool shows the coach-recommended jammed distance (typically 4 feet / 1.2 m shorter than race spacing for youth; 3 feet / 0.9 m for advanced athletes) and the bunched distance (1 foot / 0.3 m closer than race). Athletes should perform drills at reduced spacing until they can consistently 3-step before moving to full race distance. Hurdle height is also typically kept one notch below race height during most of the training season.
Common Mistakes When Setting Up Hurdles
- Measuring from the wrong reference point. For 400m hurdles, measure from the stagger line, not the common finish line — the stagger ensures each runner covers exactly 400 m.
- Using the wrong age-group spec. A coach setting up hurdles for a masters M60 athlete needs 100 m spacing with 84 cm height — not the open men's 110 m specification.
- Forgetting the finish run-in. After the last hurdle there is a fixed run-in distance (e.g. 14.02 m for men's 110m H). This is part of the official layout and must be measured correctly to ensure the race finish aligns with the track's finish line.
- Wrong weight/counterbalance position. Hurdles have adjustable counterweights; the weight setting for masters and youth divisions is different from open — check the hurdle manufacturer's markings or WMA appendix for weight position by height.
Frequently Asked Questions
How do I set up hurdles for different age groups?
▼
Hurdle height and spacing vary by age group, gender, and event. Use the official specifications from World Athletics (WA), USATF, or World Masters Athletics (WMA) for your level. Select your division and event above to get the exact height (in your preferred unit), distance to the first hurdle, spacing between hurdles, and every individual hurdle's distance from the start line. Print the result to bring trackside.
What hurdle height is used for masters athletes?
▼
Masters hurdle heights decrease as age increases. Per WMA 2025 rules: M35–M45 use 99.1 cm (39 in) for 110m; M50–M55 drop to 91.4 cm (36 in) for 100m; M60–M65 use 84.0 cm (33 in) for 100m; M70–M75 use 76.2 cm (30 in) for 80m; M80+ use 68.5 cm (27 in) for 80m. Women follow a similar reduction. Race distances also shorten in older age groups — from 110/100m down to 80m for very senior athletes.
What is the distance between hurdles in the 110m high hurdles?
▼
In the men's 110m hurdles (open/college/international), the distance between each hurdle is 9.14 m (30 ft). The first hurdle is placed 13.72 m from the start line, and the finish line is 14.02 m after the 10th hurdle — totalling 13.72 + 9 × 9.14 + 14.02 = 110.00 m. Women's 100m hurdles use 8.50 m spacing with 13.00 m to the first hurdle and 10.50 m from the last hurdle to the finish.
How many hurdles are in a 400m hurdles race?
▼
There are 10 hurdles in the 400m hurdles for both men and women. First hurdle is 45 m from the start; each subsequent hurdle is 35 m apart; the finish line is 40 m after the 10th hurdle (45 + 9 × 35 + 40 = 400 m). Men run over 91.4 cm (36 in) hurdles; women run over 76.2 cm (30 in). Masters athletes in older age groups run the 300m long hurdles over 7 hurdles instead.
What hurdle heights are used in USATF youth track?
▼
USATF youth hurdle heights step up with age: 11–12 (Midget) boys and girls run 80m over 76.2 cm (30 in) hurdles; 13–14 (Youth) boys run 100m over 83.8 cm (33 in), girls run 100m over 76.2 cm (30 in); 15–18 (Intermediate/Young) boys run 110m over 99.1 cm (39 in), girls run 100m over 83.8 cm (33 in) — matching the high school standard.
How do I calculate each hurdle's position from the start line?
▼
The formula is straightforward: Position of hurdle n = (distance to first hurdle) + (n − 1) × (between-hurdle spacing). For example, in open men's 110m H: H1 = 13.72 m; H2 = 13.72 + 9.14 = 22.86 m; H3 = 22.86 + 9.14 = 32.00 m; and so on. This calculator computes and displays all positions automatically so you can mark the track with a tape measure without doing the arithmetic by hand.
Can I use this calculator for indoor hurdle events?
▼
This calculator covers the outdoor hurdle specifications for each age group, which are the most commonly needed. Indoor hurdle events (50m, 55m, 60m) use the same start-to-H1 and between-hurdle spacings as the outdoor sprint hurdles but over fewer hurdles and a shorter total distance. Indoor 60m: 5 hurdles, 13.00 m to H1, 8.50 m between (women/HS); or 13.72 m to H1, 9.14 m between (men/HS boys). The height standards are the same as outdoor for the equivalent age group and gender.
