The Course

Leg 1

Swim — Mediterranean Sea (Baie des Anges)

2.4 mi (3.8 km) — 2 loops

Two loops in the Baie des Anges (Bay of Angels) off Centennial Beach (Plage du Centenaire), with the Promenade des Anglais as the backdrop. The course is an "M"-shaped configuration — athletes enter from the pebble beach, swim out perpendicular to shore with approximately 900m of clear water to the first buoy, then navigate the turns before heading back. Between loops there is an Australian exit: a brief ~20m run across the beach before re-entering for loop 2. Water temperature in late June is typically 20-22°C (68-72°F) — wetsuit legality depends on the official race-morning measurement (wetsuits banned above 24.5°C). The Mediterranean saltwater provides extra buoyancy. Sighting landmarks include the Old Port tower at buoy 1 and the Hotel Negresco at buoy 3. The swim exit leads directly to T1 at Quai des Etats-Unis via the Centennial Beach stairs.

Strategy Notes

  • Sight off the large orange turn buoys every 8-10 strokes. Use the Hotel Negresco and Old Port tower as secondary landmarks to avoid swimming extra distance.
  • The rolling start sends 3-4 swimmers every 5 seconds. Seed yourself honestly by expected swim time. Draft off a slightly faster swimmer for free speed — sit on their hip or feet.
  • The first buoy is ~900m out. Do not sprint the start. Settle into rhythm by 200m and find clean water.
  • Australian exit between loops: jog across the pebble beach, take a gel, steady your breathing, and re-enter calmly for loop 2.
  • The Baie des Anges can be glassy or choppy depending on wind. An easterly wind creates swells on the return leg. Practice sighting in chop beforehand.
  • Invest in quality anti-fog goggles. Mediterranean sun glare can be blinding on the eastward legs. Tinted goggles recommended.
  • Swim cutoff: 2 hours 20 minutes from start. Pace yourself but keep moving — walking the beach exit costs time.
Leg 2

Bike — Alpes-Maritimes Mountains

112 mi (180 km) — single loop 2,500 m+

The legendary IRONMAN Nice bike course is a single demanding loop from the Promenade des Anglais into the southern Alps and back. It has the steepest 0.5 km, 1 km, 5 km, and 10 km segments of any full-distance IRONMAN on earth. Athletes ride north along the Var River valley before the road tilts upward. Col de l'Ecre (km 40, 13 km at 4.9% average, 639m gain) ascends via the spectacular Gorges du Loup, passing through the perched village of Gourdon. Col de Vence (9.7 km at 6.6% average, with sections approaching 10% and peaks above 12%) is the course's iconic test. The route continues through the Parc Naturel des Prealpes d'Azur, past villages like Coursegoules and Andon, before the long descent back to the coast. After Coursegoules, there are less than 100m of climbing remaining over the final 50 km. The descents are fast (60-80+ km/h), technical, with tight hairpins requiring full concentration. The course passes through 17 towns and villages across the Alpes-Maritimes. T1 and T2 are both located at the Quai des Etats-Unis on the Promenade.

Strategy Notes

  • Pace the first 40 km conservatively. The flat Var River valley to the base of Col de l'Ecre tempts you to push — resist. Save your legs for 2,500m of climbing.
  • Col de l'Ecre (km 40): 13 km at 4.9%. Settle into a sustainable rhythm. Stay seated, spin a low gear (34x28 or easier), and eat on the lower slopes where the grade is gentler.
  • Gorges du Loup: Stunning scenery but stay focused. The road is narrow with occasional rough patches.
  • Col de Vence: 9.7 km at 6.6% with ramps above 12%. This is where the race is won or lost. Do not go into the red — you have a marathon to run. If your heart rate spikes, back off immediately.
  • Descents are technical with tight hairpins. Stay aero on straights but scrub speed early into corners. Keep hands near brakes. Avoid deep-section wheels if crosswinds are forecast.
  • After Coursegoules the course is essentially flat/downhill for the final 50 km. Spin easy, shift to run nutrition (cola, simpler carbs), and mentally prepare for the marathon.
  • Nutrition target: 60-90g carbs/hour from the start. Set a watch alarm every 20 minutes. Eat and drink on the flats, not on the steep climbs where breathing is hard.
  • Bike cutoff: 10 hours 30 minutes from race start (~5:00 PM). If you are climbing Col de Vence after noon, you need to push the pace.
Leg 3

Run — Promenade des Anglais

26.2 mi (42.2 km) — 4 loops 237 m+

Four identical out-and-back loops along the iconic Promenade des Anglais, the palm-lined seafront boulevard of Nice. Each 10.55 km loop heads west from T2 (near Quai des Etats-Unis) toward Nice Cote d'Azur Airport, passing the Hotel Negresco and the Theatre de Verdure, before turning around and heading back along the Mediterranean coastline. The course is flat, fully paved, and spectator-friendly — you pass the finish chute area on every single loop, creating both a psychological challenge (you see the finish line three times before actually crossing it) and maximum crew access. Aid stations every ~1.7 km provide water, cola, energy drink, fruit, ice, and sponges. Approximately 80,000 spectators line the Promenade by evening. The finish line is on the Promenade near Jardin Albert 1er. Late June temperatures can reach 28-32°C on the sun-exposed Promenade.

Strategy Notes

  • Walk through EVERY aid station for the first loop. Hydrate methodically — the late afternoon sun on the Promenade is relentless and there is zero shade.
  • Run/walk strategy works well: run 10 minutes, walk 1 minute through aid stations. Do not be a hero in loop 1.
  • Heat management is critical. Pour ice water over your head, stuff ice in your hat, down the back of your jersey, and in your shorts. Pre-cool with an ice vest if available before starting the run.
  • Use salt tablets and electrolytes aggressively. Sweat loss on the exposed Promenade is significant. Hyponatremia is a real risk if you only drink water.
  • Cola and flat ginger ale at aid stations are your best friends when gels stop working. Switch to real food (bananas, pretzels) if your stomach rebels.
  • The four-loop format is mentally tough. Break it into halves: "just get to halfway" then "just two more loops." The crowd energy builds through the evening — feed off it.
  • Aim for negative splits. The sun drops and temperature cools in the final 2 hours. Your best running will come in loops 3 and 4 if you pace conservatively early.
  • Final km: soak it in. The finish chute under the lights with the Mediterranean backdrop is unforgettable. You have earned every step.

Spectator Guide

IRONMAN Nice is one of the most spectator-friendly races in the world. The swim, both transitions, the entire run course, and the finish line are all along the Promenade des Anglais — you can see the athlete multiple times without moving far. The bike course disappears into the Alpes-Maritimes mountains for 5-7 hours, so plan activities during that window (explore Vieux Nice, the Cours Saleya market, or grab lunch). The Promenade is closed to traffic on race day, making it easy to walk between viewing spots. Getting around Nice: use the tram (Line 1 to Old Town/Place Massena, Line 2 to the airport) — a single ticket is 1.70 EUR and covers buses and trams for 74 minutes. Trams run from 4:25 AM to 1:35 AM. Download the IRONMAN Tracker app the night before and keep your phone charged — you will be tracking for 14+ hours.

Swim Start — Centennial Beach (Plage du Centenaire)

The beach start is dramatic. Athletes run into the Mediterranean at 6:30 AM as the sun rises over the Baie des Anges. Stand on the Promenade railing above the beach for an elevated view, or find a spot on the pebble beach itself near Ponchettes Beach and Quai des Etats-Unis. You can see both swim loops from shore — look for the colored swim caps. Key sighting landmarks: the Old Port tower (buoy 1) and Hotel Negresco (buoy 3). Watch for the Australian exit between loops when athletes briefly run across the beach. The atmosphere is electric with music, announcer commentary, and thousands of spectators. Arrive by 6:00 AM for a good spot.

Best for Swim start (6:30 AM), watching both swim loops, the Australian exit between loops, T1 exit (~7:30-8:30 AM)

T1 — Swim-to-Bike Transition (Quai des Etats-Unis)

Located at Quai des Etats-Unis, just up the stairs from Centennial Beach. Athletes exit the water, run up the beach, enter the T1 transition tent to change into bike gear, and emerge on their bikes heading onto the Promenade. The transition area itself is not accessible to spectators, but you can see athletes entering and exiting. Position yourself along the ramp from the beach to T1 or near the bike mount line on the Promenade. This is a quick spot to cheer — they will be focused but a shout goes a long way.

Best for Quick sighting after the swim (~7:30-8:30 AM)

Bike Out/In — Promenade des Anglais

The bike course starts and ends on the Promenade. You can see athletes heading out (fresh and fast) and coming back 6-7 hours later (tired but relieved). The Promenade section is flat and fast — they fly past at 35-40+ km/h — so position near the bike mount/dismount line. The course spans the entire Promenade from Theatre de Verdure to the airport. After cheering the bike start, you have 5-6 hours free while athletes climb Col de l'Ecre and Col de Vence — perfect time for brunch at Chez Theresa (socca at Cours Saleya), lunch at Le Mesclun (facing the Promenade), or coffee in Vieux Nice.

Best for Bike departure (~8:00 AM) and return (~2:00-4:30 PM). Use the 5-6 hour gap for sightseeing and lunch.

T2 — Bike-to-Run Transition (Quai des Etats-Unis)

Also at Quai des Etats-Unis, near T1. Athletes dismount, rack their bikes, and change into run gear. The transition from cycling to running is where the race truly begins for most athletes — your encouragement here is critical. Watch for body language: if they look strong leaving T2, that is a great sign. Use the IRONMAN Tracker app projected splits to know exactly when to be here.

Best for Cheering the marathon start (~2:30-4:30 PM)

Run Course — Promenade des Anglais (4 loops)

The run is 4 identical out-and-back loops on the Promenade, from near Quai des Etats-Unis west toward the airport and back. This means you can see the athlete up to 8 times (out and back on each loop) from a single spot. Pick a location near an aid station (~every 1.7 km) where they slow down — you can hand off encouragement, ice, or a cold drink. The Hotel Negresco is an excellent landmark to station yourself: athletes pass it every loop, there are cafes nearby, and it is roughly mid-course. The atmosphere builds through the evening as approximately 80,000 spectators line the Promenade.

Best for Maximum sightings throughout the marathon (3:00 PM - 11:00 PM). One spot, up to 8 views.

Finish Line — Promenade des Anglais / Jardin Albert 1er

The iconic IRONMAN finish chute near Jardin Albert 1er. A carpeted, illuminated corridor with grandstands, music, and the famous announcer call: "YOU ARE AN IRONMAN!" Get there early to claim a spot along the chute — grandstands fill up fast in the evening. Athletes who have been racing for 12-17 hours cross the line to a wall of sound. Night finishers (after 9 PM) get the absolute best atmosphere as the lights, music, and crowd reach peak intensity. The celebration and recovery area is directly behind the finish line with food, massage, and medal distribution. Awards ceremony the following morning at Theatre de Verdure (11:00 AM).

Best for The finish — arrive 30+ minutes before the estimated finish time. Night finishers get the best crowd.
