How long should I train for a triathlon?

It depends on the distance - for a sprint triathlon like the Cardiff Triathlon and Duathlon, plan 8 to 12 weeks, training 4 to 5 times weekly: 1 swim (focusing on open-water skills), 1 cycle (building to 24km), 1 run (up to 5km), 1 brick session (bike-to-run), and 1 strength workout. For an Olympic-distance race like the Croyde Ocean Triathlon, aim for 12 to 16 weeks, with 5 to 6 sessions weekly, including longer distances (e.g., 40km cycle, 10km run). EtchRock’s blog offers free training plans to prepare for UK triathlons.

What fitness level do I need for a triathlon?

Triathlons welcome all levels - for a sprint, you should be able to swim 800m (in under 20 minutes), cycle 20km (in under 60 minutes), and run 5km (in under 40 minutes). For an Olympic-distance race, aim for a 1.5km swim (in under 35 minutes), 40km cycle (in under 2 hours), and 10km run (in under 60 minutes). Build your stamina with events listed on EtchRock’s running events directory before taking on a triathlon.

Can I train for a triathlon with a busy schedule?

Yes! Train 3 to 4 times weekly: 1 swim (30 minutes), 1 cycle (45 minutes), 1 run (30 minutes), and an optional brick session (bike-to-run, 45 minutes), over 10 weeks for a sprint. Combine disciplines on weekends if time is tight - a 20km cycle followed by a 5km run is a great session. EtchRock’s triathlons directory helps you find races that fit your schedule.

How do I manage triathlon transitions on race day? Practise transitions beforehand - set up your gear logically, using a bright towel to spot your station easily. Lubricate wrists and ankles to remove your wetsuit quickly, and slip on cycling shoes while moving to save time. Athletes using EtchRock can find triathlons with detailed course guides to plan transitions on varied terrain. What gear is essential for a triathlon? You’ll need a wetsuit (for open-water swims), a road bike with a helmet, and running shoes. Bring a trisuit for all stages, goggles, a towel, and nutrition like gels for longer races. Organisers for events like the Croyde Ocean Triathlon provide gear checklists through EtchRock to ensure you’re race-ready. How early should I arrive for a triathlon? Arrive 90 minutes early to set up your transition area, collect your bib, and do a light warm-up - a 5-minute jog, a short swim to test your goggles, and a quick spin to check your bike. It’s also a chance to familiarise yourself with entry and exit points. EtchRock’s triathlon event guides provide schedules and tips to help you feel prepared at the start line. Can I race a triathlon solo or as part of a team? Many triathlons, like the Cardiff Triathlon and Duathlon, offer both solo and team options - solo racing lets you tackle all three stages yourself, while teams can split the swim, bike, and run among members, making it a fun group effort. Check EtchRock’s triathlons directory for events with solo or team entry options to suit your preference.
