IRONMAN Wales

Bristol Airport (BRS) is 2.5 hours by road; Cardiff Airport (CWL) is 2 hours. Hire a car — public transport to Tenby is impractical with bike boxes and kit bags. The A48 and A477 are the standard approach routes through South Wales.

💡 Book a large estate car or van for bike boxes — hatchbacks won't fit. Pre-book at least 3 months out as hire cars near Bristol sell out race week.

Tenby's walled town, South Beach area, and St Julian's Street are the prime locations — walking distance to transition and North Beach. Most athletes stay in rented holiday cottages or guesthouses; hotels are very limited. The town is extraordinarily compact, which makes race week logistics easy.

💡 Accommodation in Tenby town itself books out 12–18 months ahead. If you missed it, Saundersfoot (5km) and Pembroke (16km) are workable fallbacks — but you'll need a car each day.

Mandatory athlete check-in at the IRONMAN Village, typically located on North Beach or Tenby Leisure Centre. Collect race pack (timing chip, swim cap, race numbers, wristband, athlete guide). Athlete briefing is mandatory — covers course changes, weather considerations, and Welsh road conditions. Do not miss it.

💡 Read the athlete guide thoroughly — IRONMAN Wales has some of the most specific course briefing notes of any race, including rules around the narrow Pembrokeshire lanes on the bike course.

Walk the T1 and T2 areas at North Beach. Visualise your exact entry and exit routes — the transition is set on the beach sand against the medieval town walls, which is visually stunning but spatially unusual. Note the position of your bike rack number.

💡 Take a photo of the rack row and row number from multiple angles. On race morning in the dark at 05:30, it all looks different.

Pack and drop your swim-to-bike and bike-to-run transition bags. IRONMAN Wales uses coloured gear bags rather than an open transition layout in many zones. Also prepare your Special Needs bags (halfway point nutrition on both the bike and run courses).

💡 Label everything. Pack a spare CO2 and a small tube of chamois cream in your T1 bag — the bike course climbs start within 8km and your kit needs to be on properly.

Eat a moderate, familiar dinner tonight — not the carb load. Keep it digestible. Tenby has several good restaurants along Tudor Square and St Julian's Street. The Plantagenet House (inside the old town walls) and Blue Ball Restaurant are long-standing local favourites.

💡 Avoid heavy red meat and anything unfamiliar. This is not the night to experiment with local game or shellfish.

A short stroll around Tenby's 13th-century town walls at dusk is a privilege — you'll be swimming out through a gap in these very walls in 48 hours. Take it in calmly. The view from the headland over North Beach where you'll start is worth a quiet moment.

💡 Keep the walk short and gentle. Stay off your feet as much as possible today.

Mandatory practice swim window is usually open race-morning-minus-one. Swim out from North Beach, sight the buoy line, and practice your beach run entry and exit through the tunnel in the medieval walls. The water is typically 15–18°C in September — a wetsuit is almost always required. The beach entry can be rocky at low tide; note the conditions at your planned start time.

💡 Swim at the same time of day as race start (07:00–07:30) to assess light direction on the water and buoy visibility. The morning sun can blind east-facing swimmers on the outward leg.

Optional but highly recommended: ride the first 10km of the bike course to check gearing and brake function after transit. The course leaves Tenby and immediately hits the Pembrokeshire hills — you'll want to know your gears are indexed correctly before race day.

💡 Do not ride more than 20 minutes total. This is a systems check only, not a training session.

Mandatory. Rack your bike at your assigned spot in transition by the published deadline (typically 17:00). Pump tyres, attach your race number to the frame, hang the helmet on the bars. This is the last time you'll touch your bike before race morning. Do a full mechanical check: brakes, gears, quick releases, computer mount.

💡 Tape your race number to the top tube and aero bars. Double-check that your Garmin or Wahoo is charged and paired. Leave your cycling shoes clipped in if you plan a flying mount — mark your spot carefully.

Browse the athlete expo on North Beach for any last-minute nutrition, kit, or CO2 cartridge needs. This is your last chance to pick up race essentials before tomorrow. Compressport, Saucony, and IRONMAN merchandise stalls typically attend.

💡 Buy an extra pack of gels or chews if you're even slightly uncertain about your nutrition strategy. The Welsh roads offer no aid station alternatives mid-climb.

Return to your accommodation and stay horizontal as much as possible from 14:00 onwards. Read, watch something light. Prepare your morning bag: wetsuit, goggles, swim cap, timing chip (on ankle), sunscreen, transition bag numbers, morning clothes bag.

💡 Set three alarms for race morning. Lay out every item of kit in order of use — wetsuit last so it's easy to reach.

The official IRONMAN Wales pasta party and team dinner is typically held at the Tenby Leisure Centre or a marquee on North Beach. Carb-load strategically here: pasta, rice, bread, light protein. Keep sodium intake up — you'll need it for tomorrow's 10–17 hour effort.

💡 Eat your largest carb meal at lunch rather than the pasta party if possible. A very large dinner at 19:00 can still be sitting heavily at 05:30 race morning. Eat moderately here.

Race morning wake-up is typically 04:30–05:00 for a 07:00 cannon. Sleep is non-negotiable. The night before the night before (tonight) is actually more important for performance than the night immediately before race day, when nerves will reduce sleep quality.

💡 Bring earplugs. Tenby pubs can be lively on Saturday night even during race week — the town doesn't fully shut down for athletes.

Wake at 04:30. Eat your race morning breakfast: 2–3 hours before start, so food should be in by 05:00. Transition opens typically at 05:30. Walk to North Beach, body-mark with race numbers, pump tyres if needed (check pressure), load nutrition onto the bike, set Garmin to record, and suit up in wetsuit.

💡 Eat 600–900 calories of familiar carbs at 05:00 max: porridge, banana, white toast, sports drink. Nothing new. Use the portable toilet queues — they are long and move slowly.

IRONMAN Wales uses a rolling wave start from North Beach. Athletes self-seed by estimated swim time and enter the water in groups every 5–10 seconds through the medieval town wall passage. The swim course is a single 3.8km loop in Carmarthen Bay. Water temperature in September is typically 15–17°C; wetsuit is mandatory or strongly advised. Sight off the castle headland on the return leg.

💡 The exit through the town wall arch is narrow and slippery — reduce speed 50m before and run on the sides of the channel, not the centre which has a slick algae strip.

Strip wetsuit on the run from the wall exit to T1. Wetsuit strippers are provided — use them, they save 60–90 seconds. Collect your T1 bag, enter the tent, change, and get to your bike. The exit from T1 runs through the town streets — listen for the route direction from marshals.

💡 Pre-apply bodyglide or vaseline around your neck and wrists before putting on your wetsuit to prevent wetsuit rash on the swim — salt water over 3.8km will make any friction point raw.

The IRONMAN Wales bike course is a single loop through the Pembrokeshire hills and is legitimately the most demanding IRONMAN bike course in the world by elevation gain. Key climbs include Wiseman's Bridge, Saundersfoot hill (short, brutal), Ridgeway hill, New Hedges, and the infamous Wiseman's Bridge return. The course uses narrow Welsh lanes — respect oncoming traffic and marshals at junctions. Spectacular views over the Pembrokeshire National Park reward every summit.

💡 Ride the first 50km conservatively. Many athletes blow up on the early climbs chasing the excitement of race day. The second half of the course has longer sustained climbs — you need legs for them. Target power, not speed. Aid stations are every ~20km.

Return to Tenby, rack your bike, collect your T2 bag, and transition to run gear. Change socks if you have any hotspots — the run is 4 laps and wet feet from perspiration get worse, not better. Apply sunscreen and chafe cream on visible pressure points.

💡 Eat your first run-course gel immediately on leaving T2 before your stomach protests the transition from cycling position to running. Your gut needs time to adapt.

The run is 4 laps along the Tenby headland, St Catherine's Island viewpoint, and the South Beach and North Beach promenades. Undulating — not flat — with short punchy climbs on each lap. The atmosphere in Tenby town on the run course is outstanding: supporters line Tudor Square and the town walls every lap. The crowd noise is a genuine performance enhancer.

💡 Break the run into single laps mentally. Do not think about 42km — think about the next aid station. Walk the aid stations entirely and drink cola from lap 2 onwards: the caffeine and sugar combination is well-evidenced in late-race performance.

The IRONMAN Wales finish line is in Tudor Square in the heart of the medieval walled town, lit up and roaring with supporters. The announcer's 'YOU ARE AN IRONMAN' call echoes off the 13th-century stone walls. Race cutoff is 17 hours from cannon — midnight. The finish line stays open and noisy to the very last finisher.

💡 Walk through the finish area slowly — collect your medal, finisher t-shirt, and mylar blanket before you do anything else. Sit down only after you have eaten and drunk something. The adrenaline will mask how depleted you are.

The IRONMAN recovery area provides hot broth, pizza, fruit, and finisher food. Eat and drink regardless of how nauseous you feel. Wrap in the mylar blanket — September nights in Pembrokeshire drop to 10–12°C and you will be cold within minutes of stopping. Find your supporters and get back to accommodation for a warm shower.

💡 Do not attempt to drive on race night. If your accommodation is not walkable, arrange for a non-racing supporter to collect you.

Sleep as long as your body allows. DOMS (delayed onset muscle soreness) peaks 24–48 hours post-race. A late, substantial breakfast with protein, carbohydrates, and eggs is ideal. Many Tenby cafés and guesthouses cater specifically to post-race athletes.

💡 Prioritise protein this morning: eggs, smoked salmon, yoghurt. Your muscles have 24–48 hours of acute repair ahead.

A gentle 3–5km section of the Pembrokeshire Coast National Park path from the South Beach cliffs is ideal recovery movement. The views over Caldey Island and Carmarthen Bay are exceptional. Walk slowly — your legs will thank you for gentle movement more than rest.

💡 Wear compression tights and comfortable shoes. This is active recovery, not a hike. Turn around whenever your legs say so.

A well-preserved 12th-century Norman castle on the Pembrokeshire coast, set above a stunning sandy cove just 9km from Tenby by car. One of the finest coastal castles in Wales. A short visit including the beach is a perfect post-race afternoon.

💡 The castle grounds include a beach access path — walk down to the sand and put your feet in the water. Cold water immersion post-race reduces inflammation.

Allow 2–2.5 hours for Bristol Airport (BRS) or 2 hours for Cardiff (CWL). Disassemble and box the bike before leaving if doing so from the accommodation — it is much harder to do in airport car parks. Many athletes use a SciCon or Bike Box Alan case for road protection.

💡 Book the latest practical flight — you will not want to rush the morning after an IRONMAN. An 18:00 or later departure gives a relaxed Day 4.

Evening departure flight home. Use the airport lounge if available — your body deserves horizontal seating and good food. Hydrate aggressively on the flight.

💡 Compression socks are essential on the flight home post-race. DVT risk is elevated for endurance athletes in the 48 hours post-competition.
