"Cycling success" is deciding what your goals are and figuring out what you should do to achieve those goals to maximize your satisfaction and fun. For competetive triathletes and bicycle racers this stuff might be helpful. For the rest of us, who cycle just for fun and who are not interested in competition or improving our speed on a ride this level of complexity is probably detrimental to the goal. GCN has always been geared to the "harder, faster, higher" crowd with occasional segments for the noncompetitive group. I'm just pointing out that there are plenty of viewers of GCN for whom the point is not to maximize speed. I suspect your "slow cycling" segments or the ones profiling people like Hank's dad are pretty popular. I wish you had more of them in addition to segments like this one.

@@gcn I think it helps, because it is a detail in the larger picture. I like to see what heartrate does with my ride. I have discovered (what most other poeple knows without thinking about it)that going above threshold between minute 15 and 30 in the first climb on a 2,5 hour journey makes the whole journey very much harder and painful than it ccan be if i go 2 minutes slower in the first climb. The first minute in that climb i set a personal Strava record by a second, which transformed a 2,5 hour ride to almost three hours. One second ahead early in the climb- 20 minutes behind when getting home. I have experienced that I am faster on 2,5 hour rides if I stay mostly in zone 2 in the initial climbs , maybe touching zone three for short periods.

I have a lactate plus device since June! It was an eye opener for me. You can test for your lactate profile, your VLamax and what happens in the fourth hour of a low intensity ride. Additionally, testing my lactate level at threshold or VO2max intervals was an eye opener. Power is good but checking your lactate levels here and there is really beneficial.

my understanding is the zone 2 as described by Dr San-Millan is just below LT2, not LT1 as mentioned.

@nanthilrodriguez Жыл бұрын

No, "Zone 2" is steady state riding. A level of riding which can be sustained indefinitely, allowing your mitochondrial and metabolic systems to clear lactate as quickly as it is generated. Because of the upslope between LT1 and LT2, that is no longer steady-state with regard to lactate generation, and thus exceeds your 2 millimole of lactate generation.

Unfortunately I reckon Conor made the mistake of saying lactate testing enables you to train harder a couple of times. It helps you train smarter by not going too hard. The thing top athletes strive for is consistency and a gentle upward curve is preferable over short unsustainable gains, which in fairness was alluded to. Thing is, it’s habitual.. the mindset is all about smashing it! (Cue guitar solo)

@nanthilrodriguez Жыл бұрын

Definitely. Lactate testing helps you to calibrate your actual levels of exertion on a day-to-day basis, helping you to maximize the goals of your training by hitting your actual target lactate numbers, whereas watts are accurate measures of power, its not an accurate measure of rate of exertion, so measuring your rate of exertion can help to ensure that you're training the appropriate windows for a given training session.

We should definitely move away from the traditional power zones and start talking about these thresholds more. Sweetspot is the real zone 3. Tempo is a relic that is basically a conservative buffer between a poor aerobically developed athlete and a well trained athlete. We should replace tempo with lactate or proxy power and hr based LT1 tests, like the hr drift test championed by Scott Johnston of uphill athlete. The bigger base we have, the higher the LT1 hr. That is what having a wide base really means. A wide hr range along the x axis of the graph before crossing LT1.

I get what you're saying. Global Triathalon Network did do a very similar video. Nearly identical, but on a treadmill... But this video is whether or not this is going to be a new pocket gadget you see out on the road as a cyclist. That being the question posed by the video, I see it as a legitimate question. Most people get this sort of testing done in laboratories, and don't carry a device around in their jersey pocket. Will that become common place in cycling, seeing as Zone 2 has become more understood and recognized as the way to trigger metabolic adaptations for endurance performance, and considering that lactate testing is the only actual way to determine your Zone 2, being defined as 2 millimole of lactate? Seems like a valid question... even if GTN covered it last year instead of GCN... but I will say, until today, I haven't watched a single GTN video because I'm not a Triathlete.

@James-zu1ij Жыл бұрын

There is a cheaper way. Eg, if you think your threshold power is 300, pick a course of say 30 miles, then ride it at 200W exactly. Then in a few days ride at 210W and so on. Work out in your mind how comfortable you feel. i.e.I dont need to stop, I dont want to stop, I feel great. The moment the thought of wanting to stop even if its at the end of the ride, then this is lactate talking. Or you could spend £450 on a lactate analyser. Test yourself then all your mates, then go into business 🤓

@nanthilrodriguez Жыл бұрын

Incorrect. This test will only reveal your lactate threshold effort. But lactate threshold is not zone 2. Zone 2 is the level of effort you can sustain indefinitely without surpassing 2 millimole of lactate. This is the threshold that your mitochondria can metabolize lactate as quickly as it is produced. Lactate threshold however is the absolute limit of lactate generation, leading to metabolic exhaustion. So your test will find your lactate threshold, but not zone 2
