How do I pick an event that matches my interests and skill level?

Start by identifying your interests - if you love nature, opt for a trail-based event like a canicross race; if you prefer speed, choose a road-based triathlon. For beginners, try a super sprint triathlon or a short fun run; for seasoned athletes, an ultramarathon might be the goal. Consider your fitness level and the event’s terrain, distance, and support. EtchRock’s events directory lets you filter by category and difficulty to find the perfect match.

How long should I train for my chosen event?

It depends on the event - for a super sprint triathlon, plan 6 to 8 weeks, training 3 times weekly: 1 swim (0.4km), 1 cycle (10km), and 1 run (2.5km). For an ultramarathon, aim for 20 to 24 weeks, with 5 runs weekly, including long runs up to 50km. Many organisers offer advice and training plans to help you prepare, which you can often find through their event pages. EtchRock’s blog also provides training plans for all event types to support your journey.

What fitness level do I need for different types of events?

Fitness levels vary by event - for a 5km mud run, you should be able to jog 3km (in under 25 minutes); for a sprint triathlon, swim 0.75km (in under 20 minutes), cycle 20km (in under 60 minutes), and run 5km (in under 40 minutes); for an ultramarathon, run 42.2km (in under 6 hours). Build your skills with events listed on EtchRock’s events directory to match your current fitness level. Many organisers provide guidance on fitness requirements to help you prepare.

Can I train for an event with a busy schedule?

Yes! Train 3 to 4 times weekly, focusing on key sessions: for a triathlon, 1 swim, 1 cycle, and 1 run (30 minutes each); for a mud run, 2 runs and 1 strength workout (30 minutes each); for a virtual challenge, schedule runs to fit your availability. Combine activities on weekends if needed - a 15km cycle followed by a 3km run works well. Many organisers offer advice and flexible training plans, which you can access to fit your schedule. EtchRock’s events directory helps you find events that suit your availability.

How do I manage transitions during multi-sport events?

For multi-sport events like triathlons, practise transitions - set up your gear in order (e.g., bike shoes before helmet), using a bright towel to spot your station. Lubricate your wetsuit for a quick swim-to-bike change, and rehearse bike-to-run transitions to save time. Athletes using EtchRock can find detailed course guides to plan for varied terrain across events.

What gear is essential for different types of events?

Gear depends on the event - for a triathlon, you’ll need a wetsuit, bike, and running shoes; for a mud run, wear old trainers and clothes you don’t mind getting dirty; for a canicross race, bring a harness, waist belt, and bungee line for your dog. Organisers provide gear checklists through EtchRock to ensure you’re ready for your chosen event.

How early should I arrive for my event?

Arrive 45 to 90 minutes early, depending on the event - 45 minutes for shorter races like a 5km run, and 90 minutes for multi-sport events like a triathlon to set up transitions. Use the time to collect your bib, do a light warm-up (e.g., a 5-minute jog), and review the course start. EtchRock’s event guides provide schedules and tips to help you feel prepared at the start line.

How should I pace myself during my event?

Pacing varies by event - for a 5km run, start at 80fort and push the last 1km; for a triathlon, keep each leg steady (70-80fort) to last the 1 to 2 hours; for an ultramarathon, start slow (60fort) and walk hills to conserve energy over 6+ hours. Fuel appropriately - a gel for a triathlon, or regular snacks for longer races. EtchRock’s events directory provides course details to plan your pacing strategy.
