Are you planning a cycling holiday in Europe, tackling iconic climbs like the Alps, Dolomites, or Swiss mountain passes? In this episode of the RCA Podcast, Cam Nicholls sits down with RCA coach and data science specialist Ben Treble to discuss exactly how recreational and amateur cyclists should prepare for a climbing-focused cycling trip. Ben breaks down the key physiological factors that determine climbing performance, including VO₂ max, fractional utilisation, threshold power, training volume, and cycling-specific nutrition. Together, they outline an 8-week training strategy designed to help cyclists maximise their fitness, improve climbing ability, and arrive in Europe ready to enjoy every ride. Whether you're heading to the Tour de France region, riding the famous Swiss Alps, taking on Peaks Challenge, or simply wanting to improve your climbing performance, this episode provides practical, science-backed advice you can apply immediately. In This Episode: ✅ Why VO₂ max alone doesn't determine climbing performance ✅ The importance of threshold power and fractional utilisation ✅ How to structure an 8-week climbing preparation plan ✅ VO₂ max training vs threshold training for long climbs ✅ Why recovery weeks (deload weeks) are critical ✅ How to increase training volume safely ✅ The role of low-cadence climbing work and muscular endurance ✅ Nutrition strategies for multi-day cycling trips ✅ Gut training and carbohydrate intake for endurance cyclists ✅ Common mistakes recreational cyclists make before a cycling holiday Who This Episode Is For: Recreational cyclists Amateur road cyclists Gran Fondo riders Cyclists planning a European cycling holiday Riders preparing for Peaks Challenge, Amy's Gran Fondo, Tour de Brisbane and other climbing events Anyone wanting to improve their climbing performance 🎯 Learn more about RCA Coaching: https://roadcyclingacademy.com/one-to-one-coaching/ Transcript: Cam Nicholls (00:01.804) Welcome to the RCA Podcast, designed for recreational and amateur road cyclists with a focus on performance. We dive into cycling training, nutrition, strength training for cyclists and even bike fitting tips, all designed to help you train smarter, ride faster and hopefully tear your mates' legs off. So without further ado, let's dive into today's episode. Welcome back to the RCA podcast, where today I am joined by the RCA's European correspondent and data science geek, Ben Treble, who's currently in Sydney but will be in Europe by the time this podcast goes live. Hello, Ben. Ben Treble (00:43.714) Hey Cam, how are you? Cam Nicholls (00:45.656) Good, thank you. So today, because you're heading over you're escaping actually you've timed this pretty well now. I'm just talking I'm thinking about this out loud. You're you're you're about to hit the depths of winter in Sydney. And Sydney gets pretty cold. People don't think it does, but it's actually it's a pretty cold winter. And you're moving to Europe, you've got a one way ticket, you're gonna be in Switzerland, one of my favorite places in the world. So you're basically heading into you're going from one summer season to the next summer season. You're gonna bit you're an expert in summer seasons, essentially. So I thought it would be a good podcast topic to talk about what's the best way not to prepare for a summer season, because we've kind of, you know, you should have been doing that two, three months ago. But maybe you might want to blend that into the conversation. But more so, you know, we're at the start of the summer season. How are we, you know, as a recreational and amateur road cyclist who's training anywhere between sort of six to twelve hours per week, depending on the person. We might have some goals to, you know, do some Fondo events, do some big climbs. How are we going to tackle the summer season? What's the best approach? Ben Treble (01:50.926) yeah, I think for me the context here is probably like a bit of a focus on climbing. So it's pretty hard to go over to Europe and not do climbing. I am a s more of a sprinter myself, so why I picked Switzerland as a location is beyond me because I'm definitely not a climber, but you can't really go anywhere without going over some big mountains. Cam Nicholls (02:15.458) Yeah, and I think this is like relevant to, you know, most people going into their summer seasons because let's face it, even though we don't have huge climbs here in Australia, when people are looking at their summer season, you know, so many people in Australia, you know, peaks has become the biggest fondo event. You know, they target peaks and there is a lot of climbing in peaks. And even some of the smaller fondo events, like Amy's, for example, what's the first thing you do? You go up a fifteen, twenty minute climb and then there's another climb in the middle. even Tour to Brisbane, which is you know, UCI qualifier, there's a fifth 10, 15 minute climb in the middle or wherever they put it because they change the event every year. So climbing isn't just a European thing. I know you're trying to rub salt in the worm because you've got amazing climbs over there, Ben in Switzerland, but you know, I think it's relevant no matter where you are in the world, because most events have significant climbs. Ben Treble (03:10.274) Definitely. Yeah. I mean Tura Brizzy, I can think of two athletes where, you know, the performance determinant was the climb. So, you know, it might not be a one hour, two hour climb. Maybe it's only fifteen to twenty minutes depending on your pace. But it's still a big determinant in tour of Brizzy and it's sort of a in some respects it it's a it's a speed hump in the what, one third of the way in. So it's but still it's super important. So climbing does become very important. I guess I just wanted to talk a bit around a couple different things on this topic. The first is probably what's important in determining climbing performance. So we'll stick to a bit of a focus on climbing and then we'll talk a little bit more around like people who go to Europe. I can think of a number of athletes I'm working with right now who are planning European holidays. That's either from North America, from Australia. I've even had athletes who wanted to prepare because they were in Australia and just going down to Bright, which is a very famous alpine region in Victoria, where there's a lot of big climbs, which don't don't underestimate. They are equal to many of the big climbs in Europe. They might not have the same altitude, but you can get a similar elevation profile. We're talking, you know, Mount Hotham as a climb in terms of total elevation is massive. It beats probably half the European climbs. Cam Nicholls (04:33.078) Yeah. How many meters do you hit in Hotham? Are you over fifteen you're definitely over fifteen hundred. Did you hit over two thousand? Ben Treble (04:40.024) think you do get two at the very top. Cam Nicholls (04:42.604) That t two thousand, from my understanding of when I climbed the the glibia many many moons ago was altitude actually kicks in at around five hundred meters. Although you probably it's probably quite subtle. Or even a few hundred meters it actually starts kicking in. But once you get to sort of fifteen hundred, two thousand, then the effects are really significant. Ben Treble (05:05.846) one eight four five Cam Nicholls (05:07.788) One eight four five. There you go. Ben Treble (05:10.254) There you go. Anyway, yeah, I think the first thing we should talk about is VO2 Max. We've talked about this a lot on the podcast. I think it's a big topic, but VO2 Max, we often talk about training it to have a higher VO2 Max. Lots of people walk around with their garments, which estimate their VO2 Max. You can think of that, it's like the the engine size, right? You can have a 600 horsepower car, but it doesn't necessarily mean that you've got the you know, horsepower or the fuel lines to feed enough fuel into the engine to actually achieve and utilize that power, right? Like you need all of the bits underneath. What is your utilization of the engine? So we know this is true. You can see people who have high VO2 maxes, but don't seem to be able to reach the same performance levels of other athletes with the same VO2 max. Cam Nicholls (06:05.269) More. Ben Treble (06:06.424) So why? Because the fractional utilization of VO2 Max is lower. Typically the way that we consider fractional utilization of VO2 Max is at your threshold. When we're talking threshold, I'm talking maximal lactate steady state, gold standard. For everybody on the podcast who don't know what that is, you can think of it as your critical power if you want to equivalent FTP. So threshold at w when you ride at your threshold, let's say it's 200 watts, 250 watts. What percentage of your VO2 max are you holding? Really well trained athletes are going to be, you know, using 85% or higher of their VO2 max at threshold. What does that mean? They're relying more on the aerobic energy system and less on the glycolytic. So they're going to use less glycogen, which is one of your, you know, most valuable resources for fuel. So you're going to conserve that glycogen. For later. Let's you having a high fractional utilization lets you ride at a higher intensity for longer, relying on less glycogen. Cam Nicholls (07:14.988) So less lactate production. Ben Treble (07:17.474) Yeah, exactly. Cam Nicholls (07:19.69) Okay. So that's important for climbing. Ben Treble (07:23.532) I should reference it's not necessarily less lactate production, it's a higher clearance rate. You're able to utilize lactate better through the aerobic system. Cam Nicholls (07:32.886) Okay. Because when you started to talk about VO two Max, I was like, well, wait a second, aren't aren't we talking about long climbs? Don't we aren't we just worried about sort of ar
