THE TERM “PHASE RATIO” IS USED BY COACHES TO REFERENCE THE RELATIONSHIP BETWEEN THE HOP, STEP AND JUMP PARTS OF THE TRIPLE JUMP – AND HOW THEIR DISTRIBUTION CONTRIBUTES TO OVERALL DISTANCE
MANY young triple jumpers learning the event will usually have a very short step as they over-hop and then can’t transfer optimally into the jump.
Obviously proper conditioning and specific training over time will have a huge effect on distance and this may of course also influence the ability to travel further.
The triple is also one of the toughest of all athletic events, as huge forces have to be overcome on each phase – some research puts these at over 12 times bodyweight.
Ideally, for initial understanding and to set in context what follows, there should not actually be too much variation between the three phases of the event – each should be around 30%-35% of total distance. However, subtle variation of these “thirds” can, according to research, have a crucial influence on total distance achieved.
At the 2018 World Indoor Champs, Will Claye’s winning leap of 17.43m comprised of a 5.93m hop, a 5.65m step and a 5.94m jump (had he been up to the limit on the take-off board he would have achieved a distance of 17.51m).

Carbon Footprint
You'd have had to have been running on a different planet to miss all the recent debate about carbon-plated shoes. The talk of bans and performance enhancement has been so widespread that even non-runners are asking their running friends about the potentially magical footwear.
Trail time
WHEN looking for a trail or off-road running shoe, it’s often all about the grip. However, given that no two paths are the same, careful consideration is required. What’s the terrain like where you’ll wear the shoes the most? If you’ll be negotiating soft, wet and muddy conditions then look for deeper lugs. For tackling gravel tracks and forest trails then more evenly spaced lugs will work better. When it comes to cushioning, consider how hard the ground will be; if it’s soft then you’ll be fine in low-profile shoes, but on those firmer tracks reasonable cushioning will be called for.
Stay neutral
EVOLVING every year, if not month, neutral cushioned shoes are seeing developments in cushioning materials and dynamics at a pace which is nothing short of astonishing. The latest models feature new polymers in the midsoles to give them a cushioned feel while at the same time keeping their weight to a minimum. Give them a spin and choose the most comfortable for mile after mile of shock absorbing running.
Support network
WHEN it comes to ‘over-pronation’, a common question is ‘how much is over?’. With no hard and fast rules, it’s best to choose a shoe that instinctively feels right. Gait analysis can often assist in helping you make this choice and your specialist running store is always a good place to start if in doubt. To help you make that choice, here’s a selection of some of the best ‘support’ shoes around.
Need for speed
THE racing shoe segment of the market is becoming somewhat split. This is partially due to the rise of carbon-plated footwear but also the fact that many shoes are becoming much lighter. Here we take a look at some of the leading contenders to toe the line in.
Gadget show
WITH technological products to enhance every area of life, running is now no different. From headphones to treadmills, the devices to aid performance and recovery are endless. Here we take a look at some of the latest gadgets and gizmos to enhance your training.
