Researcher pushing for international standard for mapping trail running events in bid for Olympics inclusion
An avid trail runner is mapping every twist and turn of the trails around Brisbane's Mount Coot-tha in an effort to bring much-needed precision to the growing sport.
University of Queensland research scientist Raimundo Sanchez has covered the trails hundreds of times with a professional GPS.
Unlike a regular marathon or running event that can be measured using a calibrated bicycle, accurately measuring trail runs is an endeavour in science and technology.
"When you run in the trails, the mountains have a ragged shape and the complexity of the terrain makes it difficult to capture with regular tools," Dr Sanchez said.
There's no international standard for how trail running events are measured, which Dr Sanchez said was hindering the sport from being taken more seriously.
"That's what I'm trying to mitigate," he said.
"I'm trying to develop a reproducible way to compare distances and elevation gain in different trail running races anywhere in the world."
Trail run organisers can use a variety of ways to measure and plot out an event.
"I've seen races where they design the route solely on the computer and don't even step onto the trails. Others use a proper GPS device or a smart watch," Dr Sanchez said.
Not all GPS devices are the same either. It can depend on the resolution of the measurements taken or how accurate it is.
A professional-grade GPS can be accurate to within a few centimetres whereas an average smart watch can be from one to five metres.
That might be fine for an amateur run, but Dr Sanchez said there needs to be a globally accepted standard of measurement for international events.
"If you measure each second it will give you a different distance than if you measure every two seconds," Dr Sanchez said.
"It's important to define which is the standard that we want to adopt."
Dr Sanchez recently tested his method at the Brisbane Trail Marathon and said he hoped to standardise all Queensland races in the coming months.
"If we as a trail runner community want our sport to grow and to become a more mature sport, if we want our sport to get to the Olympics for example, we will need the sport to get serious and to develop and adopt certain standards like this one," he said.
Michael Duggan is heading a campaign for trail running to be included in the 2032 Olympic Games in Brisbane.
He said Mr Sanchez's research is a "world first" and will help athletes understand how their performance measures globally.
"One of the things that we've really struggled with for a lot of years is the ability to be able to measure in a consistent way globally the types of trails that we run on," Mr Duggan said.
"It's very important for things like world records to ensure that trail running metrics are spot on."
Brisbane's local Olympic organising committee is set to reveal the six sports it will endorse to include in 2032 within the next 18 months.
Mr Duggan believes trail running has a good chance of making the cut.
"That's because of its growth, its diversity and the size of groups that are actually coming out of the woodwork to join trail running as an amazing new sport."

Reigning horse of the year Pride Of Jenni to visit Yarraman Park stallion I Am Invincible this breeding season
Yarraman Park has confirmed that its three-time champion stallion I Am Invincible will be the first mating for reigning horse of the year Pride Of Jenni this breeding season. I Am Invincible, who will command a $220,000 service fee this season, leads this year's sires tables for both individual winners (180) and two-year-old stakes winners (5). He's the sire of champion sprinter Imperatriz and this year produced Vinrock, the winner of the Group 1 Sires Produce Stakes in Sydney. It looks a match made in heaven with Pride Of Jenni, a winner of 10 races – including her dashing victory in the 2024 Group 1 Queen Elizabeth Stakes – and more than $10 million in prizemoney. Pride Of Jenni's owner Tony Ottobre said in a Yarraman Park announcement that he was 'in awe' of what I Am Invincible had done in his stallion career so far. 'I did look at the top stallions that were already here and I Am Invincible came up as a really good cross with her line of Street Cry, but also the fact that it's doubling to a superstar broodmare, Eljazzi,' he said. 'Eljazzi being the mother of Rafha, being the mother of Invincible Spirit. And Eljazzi, who's the mother of Al Anood who's the mother Pride Of Dubai (Pride Of Jenni's sire).'

A peak in the solar cycle means we're getting spectacular aurora australis sightings — for now
We've been treated to some stunning aurora australis light displays over the past few days, but don't expect the glow to last forever. The Sun's 11-year cycle means we're currently in the midst of an explosion of aurora activity. But that'll simmer down soon. It's a phenomenon when the sky in the Southern Hemisphere is lit up by glowing whirls of colour. You'll also hear it referred to as the southern lights. "Australis" comes from the Latin word for "southern". In the Northern Hemisphere, it's called the aurora borealis, or the northern lights. Geomagnetic storms. It's triggered by something called coronal mass ejections. "A coronal mass ejection is the literal ejection of material from the Sun out into space," Australian Space Weather Forecasting Centre (ASWFC) forecaster Andrew Jackling says. This sends charged particles from the Sun towards Earth, causing geomagnetic storms that can disrupt Earth's magnetic field. "Kind of like in a normal thunderstorm, your shutters on your house would get a bit rattled by the wind and the rain," he said. In a geomagnetic storm, the disruption can cause atoms of oxygen and nitrogen in the atmosphere to emit bright, colourful light. "There was a large solar storm on the 31st of May," Australian National University astrophysicist Brad Tucker says. "The storm was large enough to trigger a G4 storm on Earth. "The scale is 1-5, like cyclones, with G5 the largest." Here are some of the latest photos, posted to the ABC's Weather Obsessed Facebook group: While auroras are usually limited to the southernmost parts of the country, there were sightings as far north as Tamworth in New South Wales. And a big part of this is because of where we are in the solar cycle, which goes for roughly 11 years. "The current solar cycle began in 2019, since which time solar activity has generally increased as the Sun progresses toward solar maximum, which officially began in October 2024," Mr Jackling says. And that means spectacular auroras. "During solar maxima, which we are at, the Sun produces more storms, and more extreme storms," Dr Tucker says. "The activity is stronger so it is producing more of these." But it's not just the individual storm from the past few days. We've had some fairly spectacular aurora displays over the past year — check out the ABC's collection of photos from January, October, September and last July. However, the most notable aurora displays happened in May 2024, when a G5 storm hit Earth. It was the biggest geomagnetic storm we'd seen in 20 years, NASA says. While it didn't cause any catastrophic damages, the event was so big it was given a name — Gannon storm — and was the subject of a big NASA study. The solar maximum may continue for another year or two, Mr Jackling says. "By 2027, solar activity is likely to have reduced from present levels, making geomagnetic storms and subsequent auroral displays less likely to occur," he says. However, it's hard to tell exactly how long the aurora boom will last. "Every 11-year period of maximum activity varies in strength," Dr Tucker says. "Just like summers vary in how hot they are, or how wet/cold winters are, same, with the Sun, so some periods are better and others are less. "This has been a good period." No, they could still happen. "Significant space weather can occur at other times in the cycle too," Mr Jackling says. However, aurora australis activity during this time might not be visible as far north as we've been enjoying lately. So aurora chasers may have to travel much further south. "There is still an often low level of activity in the quiet years that you can get, but you need to be very near the south or north pole, which is why people make trips to the Arctic circle to see them," Dr Tucker says. Also, it's important to remember that the solar cycle means we'll come back around to another solar maximum — we'll just have to wait about a decade. Yep. "The northern and southern lights are affected equally so they will reduce as well," Dr Tucker says. However, people in the Northern Hemisphere have a better chance of seeing an aurora. "It is generally easier to see the northern lights than the southern lights due to the geographic distribution of land in the northern hemisphere, where there are more populated areas closer to the northern polar region," Mr Jackling says. "This is true at all times of the solar cycle." The ASWFC, which is part of the Bureau of Meteorology, sends out geomagnetic storm alerts via email. If you sign up to the ASWFC alerts via this online portal, you'll get an email when there's an alert.
