Fitness tested in a cool room doesn’t tell you what happens when the heat is real \u2014 and for anyone racing somewhere hot or humid, that gap matters. This test exposes you to a controlled hot, humid environment on the bike and measures how much your physiology drifts as thermal strain builds, at the exact same power output throughout.<\/p>\n
The structure is a fresh-baseline \/ heat-exposure \/ heat-stressed re-test sandwich: a 10-minute steady hold at target power fresh, mask on; a 30\u201360 minute block in the hot room to build real thermal load, mask off so you can breathe and fuel freely; then an identical 10-minute hold at the exact same watts, mask back on. Because the work rate never changes, every difference between the two holds is what the heat cost you, not a change in effort.<\/p>\n
Four markers are compared, each banded independently, with heart rate as the primary heat signal:<\/p>\n
– Cardiovascular strain (HR) \u2014 the clearest heat marker; a rising HR at the same power shows your body diverting blood to the skin to shed heat
\n– Ventilatory drift (VE) \u2014 the respiratory cost of the thermal response
\n– Economy creep (VO2) \u2014 oxygen cost for the same power, i.e. movement economy decaying under heat
\n– Substrate drift (RER) \u2014 how far your fuel mix shifts toward carbohydrate under thermal load<\/p>\n
Your report also translates the room’s temperature and humidity into a WBGT heat-stress score and an equivalent dry-air temperature, so you know exactly how hard the conditions were \u2014 not just what the thermometer said.<\/p>\n
Biomechanics, lightly: alongside the physiology, IMU sensors log a light on-bike movement and postural stability check through the heat-exposure block \u2014 a supporting read on whether fatigue and heat are affecting your position and form, not the main focus of this test.<\/p>\n
What you’ll get:<\/p>\n
– Cardiovascular strain (% HR rise) and thermal-strain classification \u2014 your primary heat result
\n– Ventilation, economy and substrate drift, banded
\n– WBGT heat-stress score and equivalent dry-air temperature for the room you were tested in – A light IMU-based form\/stability flag alon
\n– A heat-acclimation training plan targeted at whichever marker drifted most<\/p>\n
Before you test: arrive fasted for 4+ hours, no caffeine or stimulants for 6 hours, no heavy legs or high-intensity work in the 48 hours prior, and arrive well line invalidates the heat comparison, sothese matter.<\/p>\n
Coming soon: an altitude-resilience companion test in our hypoxic chamber, for athletes who need to know how they cope with thin air as well as heat.<\/p>\n

A controlled heat-and-humidity test that shows how your body actually copes once the temperature climbs \u2014 not just how fit you are in comfortable conditions. A fresh baseline effort, a heat-exposure block, then an identical-load re-test reveals exactly how much your heart rate, breathing, economy and fuel mix drift once thermal strain builds. Cycling, at your own power. Includes a light IMU-based form check alongside the physiology. Altitude resilience (hypoxic chamber) is coming soon as a companion test.<\/p>\n[ameliastepbooking service=18]\n","protected":false},"featured_media":1595,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[91,87,176,90,85],"product_tag":[],"retreat-category":[199,144,197],"class_list":["post-29228","product","type-product","status-publish","has-post-thumbnail","product_cat-assessment","product_cat-body","product_cat-performance","product_cat-service-types","product_cat-services","retreat-category-body","retreat-category-performance","retreat-category-services","first","instock","purchasable","product-type-simple"],"booking_location":null,"booking_location_type":null,"booking_duration":null,"booking_duration_unit":null,"booking_buffer":null,"booking_cost":null,"booking_resources":null,"exclude_global_add_ons":false,"addons":[{"name":"Biomechanical Analysis","type":"checkbox","position":0,"required":false,"title_format":"label","default":"","description_enable":false,"description":"","placeholder_enable":false,"placeholder":"","display":"select","restrictions_type":"any_text","adjust_price":false,"price":"","price_type":"flat_fee","restrictions":false,"min":"0","max":"0","options":[{"label":"Biomechanical Analysis","price":"100","price_type":"flat_fee","image":0,"visibility":true}],"id":1786461034}],"acf":[],"yoast_head":"\n
