HEAT STRESS GUIDANCE FOR ATHLETES

ESS has been leading the way with research and guidelines for Heat Stress at Trail Running events since 2014.
We use the Wet Bulb Globe Thermometer Heat Stress Index that incorporates ambient temp, humidity, breeze (or lack of) to create a value to give event organisers customised information for their event in warm conditions that factors in their activity, the duration and runner cohort.
Using that data we can make a reliable forecast of whether we’ll see conditions where we could see participants collapse from heat and can work with organisers to come up with Heat Mitigation measures to keep the event going even on high heat stress days.
Sport Medicine Australia has just released an update on Heat Stress for sport and it’s great to see that the guidelines that ESS has been creating for 11 years is validated by the new SMA recommendations.

If event organisers want industry-best advice that’s informed by years of evaluation and experience drop a line and we can help you run events more safely on hot days.

ESS HAS BEEN RUNNING WILD SINCE 2012!

We’ve just clocked up 13 years providing safety consulting, comms and first aid to the excellent Running Wild Trail Association!
Running Wild stage a calendar of Blue Mountains events over spring to autumn and all have become iconic in their categories including the Solitary Ultra, one of the most beautiful, remote and toughest short ultras around. The Kedumba Half is a brutal “little” jaunt down and back up Kedumba Pass, Glenbrook Marathon is a loop course based out of Euroka Clearing and “Saints and Sinners” is a social lap race format in the mid-mtns bush near Springwood.
It’s been a real honour to work with the community-minded Committee over so many years and to contribute in our small way to these great events and the wellbeing of thousands of trail runners.
Running Wild events are a great intro to Trail Running for Blueys and Sydney people and are friendly and welcoming for enthusiasts and fast runners.
The Narrow Neck Night Run is coming up on 15/11/25 - check it out.

Working with the team from Single Track Events to get ready for Hounslow Classic this weekend. Here's our first weather report. It's looking like ideal running conditions and maybe some fast times.
ESS provides the Medical team, remote first aiders, the radio repeater network, advice around weather and conditions and the water filtering/pumping for the new water point in Blue Gum Forest.

WEATHER UPDATE - HOUNSLOW CLASSIC Marathon Sat 13/9/25 & 17km event Sun 14/9/25

• After some rain, heavy at times on Wednesday and lighter on Thursday weather conditions will clear for Friday and the weekend.
• Trails will be wet underfoot and puddles will remain in places.
• Damp rocks in shady and/or sheltered areas such as Grand Canyon will stay slippery into the weekend.
• River level for the crossing at Blue Gum Forest will be a little higher than usual. Possibly knee deep but we’ll get a better idea in coming days.
• Temps at Allview and cliff top tracks will top out in mid-teens (14C to 16C both days).
• Expect temps 10C hotter than that on north facing slopes in the sun (eg the climb up to Lockleys).
• Winds - light westerlies both days.
• Skies alternating sunny/cloudy both days.
• Humidity will be at the lower end of the scale (good news).
• Summary - ideal running conditions. We might see some fast times.

More accurate reports coming daily from now as our data becomes more accurate. Watch this space.
