[H3] Heat training and sweat testing to help you perform at your best
We use our heat chamber to acclimate athletes so that they’re ready to perform in the heat. Recent research has shown that heat training is also a strategy to improve performance in temperate conditions, making it applicable to all athletes looking for an edge. Beyond heat acclimation, we offer a range of performance tests and specialist training services including:Sweat Rate Testing to help you figure out how much you need to drink in training and racing
Sweat Sodium Concentration Testing, which tells you how much sodium you lose in your sweat to help you dial in your hydration strategy
Lactate Threshold Profiling to help you refine your training zonesHeat training is a powerful performance tool which is largely underused by the average athlete.Victor Campenaerts - Tour de France Stage winner

[H2] Sweat Testing
Sodium is the key electrolyte you lose in your sweat and it’s crucial to your hydration status. The thing is, everyone loses a different amount of sodium in their sweat, from as little as 200mg of sodium per litre, to as much as 2,000mg/L. This is largely genetically determined and our at-rest Sweat Test can tell you how much you lose so you can dial in your hydration strategy.
[IMG: Sweat Testing]
[H2] What it involves
Sitting comfortably for ~30-45 minutes whilst our Sweat Test kit stimulates a small patch of your forearm to sweat maximally and we collect a sampleNo needles, no exercise

Arriving by train?Hinton Admiral is the closest station but it’s tricky to walk to the lab from there, so please talk to us about picking you up.Arriving by car?Our address is: Old Sawmill, A35, Lyndhurst Rd, Hinton, Christchurch BH23 7DX
Here’s the What 3 Words location: https://what3words.com/next.refreshed.handbook
Our HQ is a lovely converted Sawmill with a gravel driveway, literally just off the main road.
When you arrive, if they’re free, you can park out front in the spaces to the left of the building.
Or head through the gates on the right and park around the back. Please just keep the channel on the right free so delivery vehicles can access the warehouse at the back of the plot.
Then head in via the central glass “patio” door at the back of the building and someone will greet you.

[H3] Frequently asked questions
Do heat acclimation sessions have to be on consecutive days?Research suggests that consecutive doses of heat are the most effective at developing adaptations. But, we know it’s not always possible to fit that around busy lives. To build adaptations to the heat, a minimum of 5 sessions within 7 days is recommended. This initial build up phase can be followed by a minimum of 1 session per week (preferably 2+ per week) to maintain some of the adaptation for extended periods of time.What do I have to bring with me to the sessions?Cycling? Bring your usual cycling kit. We recommend wearing bib shorts, cycling socks, and cycling shoes, with the addition of a sports bra or base layer for women. Running? Bring your usual running kit (shoes, socks, shorts and a light top). We’d recommend wearing a singlet or vest as you’ll be sweating buckets! Please bring along a change of clothes for afterwards, and any exercise tracking device you normally use such as a Garmin/Wahoo cycling computer/watch to track the sessions if you wish to.Am I able to bring my own bike?Yes! We have direct drive trainers from Elite to set road and TT/triathlon bikes on. We have a range of cassettes and freehubs to fit all road groupsets. Am I able to leave my bike with you instead of taking it home? You can leave your bike with us for the duration of your acclimation sessions.Do I have to bring my own bike to each session?No, we also offer sessions on a Stages smart bike, where you can adjust the position to suit you.Can I run or ride?You’re able to choose running or cycling to your preference. But, for best results, choose the modality you do more frequently or will be racing in. For triathletes, it can be beneficial to do acclimation sessions near to each other on the same discipline each time, but it may be more beneficial to conduct heat training sessions while running as heat stress is greater when running vs riding (in the same conditions and the same relative intensity).What is your cancellation policy? You are allowed to cancel up to 12 hours prior to the session. Cancellations within 12 hours of the booking and no shows won’t be refunded unless there are extenuating circumstances. Please email our Athlete Support crew at lab@pfandh.com and they’ll get you sorted.Can I train that day while completing heat acclimation trials?Yes, you are welcome to continue your regular training, with two caveats. We recommend reducing the volume and intensity of any additional sessions you do, especially within the first 5 days of heat acclimation sessions. Once you have conducted 5 sessions in the heat, you will start to be less impacted by the conditions and be better able to do more intense, quality work.What happens if I buy a pack and then am unable to attend 1 or more sessions (due to any reason such as sickness, injury etc)?All individual sessions/packages are valid within 12 months from the date of purchase. Please reach out to lab@pfandh.com with any questions on how to book sessions if you have any trouble.

[H2] What athletes have to say
(1788 reviewers)“The experience was fantastic. In fact, it was so good that the only "problem" is that it felt "too good to be true (and free)".” - Mark“One of the survey questions here was about "how likely you are to book more time in the future if you have more questions". While I'd love to do that, I feel hesitant because I don't know how you make the economics work with offering this level of support, and I definitely want your business to succeed!” - Assaf“For me it has simplified what I should be doing and highlighted areas of hydration and fuelling I’ve had wrong, eg not really needing electrolytes for short training sessions and also how to simplify fuelling while competing.” - Dave“The experience was excellent. The advice is working!” - Ali“Excellent service that I stumbled upon. Knowledgeable and friendly. No hard sales during the phone call which was refreshing.” - Vivi“Huge thank you to PF&H. The call was hugely informative, friendly and knowledgeable. There was no hard sales push. My questions were answered clearly and queries clarified. I love the product already and will continue to use for my up coming Ironman.” - Iain“The whole thing was outstanding, and I would love to talk with the team again; this is such a cool experience, and I can't believe the first session is free! There is so much information from experts.” - Maaike“There was a lot of information discussed which is great, but one thing I appreciated greatly was the follow up that summarized things and allowed me to refer back to the advice.” - Karen“I can't believe this was free, and no sales expectations at all. They listened better than anyone I've spoken to about this (I talk a lot!), and offered such well thought out advice. They clearly know their stuff. Thank you Precision for raising the bar!” - Samantha
