• Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.

Best back stretches for triathletes

Will I still get a benefit if I do my bike training with someone slower than me?
  In short, the answer is yes, you will still benefit from doing some of your bike training with someone slower than you.

The ultimate guide to your first triathlon
  To minimise the risks of coming unstuck at your first triathlon, we’ve asked some top coaches to provide expert insights to take you through that first event, from the nail-biting build-up to the celebratory beverage after the race, whatever triathlon distance it is; super sprint, sprint, standard distance – or, for the crazies among you, something even longer.   How fit...
What if I finish last in a triathlon?
  Worrying about finishing last is a concern many people have when racing a triathlon for the first time but it shouldn’t put you off giving triathlon a go.

What's a brick session?
  A brick session is a training set that involves more than one discipline/sport back-to-back. The most common example in triathlon is the bike/run brick, where a bike session will be followed by a run.   An example could be a 30min road bike ride followed by a 10min run straight away after (you can steadily build up the duration and intensity...
What's the shortest triathlon?
  The shortest form of triathlon at an event is generally the super-sprint distance triathlon or what can be called the ‘Starter Triathlon’.

The triathlete's complete guide to heart-rate zone training

But while it’s true to an extent, those who stick with endurance sport soon learn a harsh lesson:...
Triathlon times: What’s a good triathlon time?
  Born in the early 1970s at the San Diego Track Club, modern triathlon has grown enormously over a relatively short period of time into a variety of popular formats.   There are now thought to be around 100,000 active participants in the UK alone, and the sport has seen tremendous growth over the last decade.   We’re not bad at it either:...
What makes triathlon’s strongest cyclists so fast?
  I might be biased as I’m primarily a cyclist, but, especially in middle-distance and long course non-drafting events, it really is all about the bike.   Time-wise it constitutes the biggest proportion of the event and not only can a strong rider make up huge chunks of time on the ride but, if they're able to put in a decent bike...
