Ever wondered about what its all about? On chatting to my family and freinds triathlon is commenly mistaken for being a challenge only for extremely fit people, well let me tell you the truth.

Can you swim, cycle and run? Then triathlon could be for you! 

This blog will give you an idea of cost, commitment and where to start… from main bulk item purchases, training time and the overall experience. 

How much will it cost?

The more you get into the world of triathlon - the more the temptation is to spend. It's not a cheap hobby by any means, but there's plenty of plus points. From making new friends to improving your fitness - and we guarantee you'll start eating healthier and drinking less alcohol too!



Membership of a local pool (£20-50 per month) will encourage you to swim regularly. The swim part of most sprint triathlons is indoors so no need for a wetsuit just yet. 


Wetsuits add buoyancy, but cost £100-£600, so keep that in mind. Make sure you get yourself fitted, if it's too big it will rub and slow you down. Tailor made suits are available, as well as off the shelf options.


A good swim suit (no boardies guys, they slow you down heaps). £15-20.


There's a huge array of goggles out there from about £20-£40. A pool set (and a lake set if you're competing outdoors) will suffice, although anti glare models are also available for sunny conditions. 

Swim hats are usually given to you on race day.

Entry level road bikes cost about £600 but search around - there are plenty of great second hand bikes online. Check if your company offer the Cycle to Work Scheme for savings of up to 42% off a new bike! Specific triathlon geometry bikes (if you really get into it!) will set you back £1000-£5000+ but are more comfortable and offer the most seamless transition to the run.


Most important of all - make sure your bike is the correct size for you. Seek advice from a bike fitter. They aren't loyal to any brand, they just want to make sure you get the right bike for your physique. Bike fits cost about £100, but if you buy a new bike from a shop they may throw in a bike fit for free.

As you improve a bolt on triathlon bar set up is worth some thought (£40 - £300). It will make races more comfortable, faster and aid you coming off the bike ready for the run.


To improve your fitness consider supplementing your outdoor rides with some coaching from a Watt Bike facility (£10) or attend a few spinning classes (£5/class).


Learning to use clip in cycle shoes will transform your training and is highly recommended for any distance over a sprint. £40-£300 for shoes and pedals. 


A helmet is a must. Make sure you try before you buy. Cost is £40+ for a basic model. We could talk more bout specific lids for specific races but we fear we may lose you. specific aero lids £120-£300



Expect to pay anything between £80-£100 for a good set of trainers. 


Your usual gym lycra will be fine for running and cycling as long as it's breathable, all-weather gear. Consider a high vis top for winter/early morning/late evening training (about £30) and definitely invest in some padded cycling shorts to protect your crown jewels! Basic shorts start at about £20, but you get what you pay for so think about spending a little more if you want to make sure you're comfortable on longer rides. A triathlon suit is worth what you pay for, for optimal comfort £60-£200.

How much do I need to train?

This is entirely up to you and depends on how well you want to do! The famous Ironman has to be completed in a maximum of 17 hours, and suggests a training week of over 14 hours - which is a lot of swimming, cycling and running!
