No Lactate threshold test for cycling?

Hi, I am an injured runner getting much more into cycling going forward, and notice that my perceived exertion and heart rate are quite different from when I run. This makes sense given how I am not fighting gravity and using fewer muscle groups, but I was wondering about training, zones and getting a lactate threshold for cycling so that I can begin to match various heart rates with perceived exertion (which I am much more accurate with when I run...when I 'just know' that my pulse is climbing over 150, say). Any idea why they left the LT test for cycling off the watch, or am I missing something, and what to do instead?
  • Numerous places on the inter web to find guidance for doing your own. Here's a workout you can program:
    1. Warm up for 15 minutes
    2. Ride at a pace you can hold for 30 mins
    3. Continue riding at that pace.
    4. Cool down for 15 minutes

    Your LHR is the average HR achieved in step 3.

    Works for running too.
  • FTP is your friend on the bike in this regard. Will need a power meter of course.

    Thanks Tim, yes I did look into that after I dropped the $$ on the bike, but then I went and bought the 935, so...!

    Thanks Philip, I will try that, but was just wondering if there was a reason there is an LT test for running on the watch, but not cycling.
  • Probably because, as Tim notes, there is more of a tendency to focus on power on a bike. I don't have a power meter so I use HR. I use PerfPro Studio for indoor training on the bike and can get virtual power from that which is useful for indoor training and does allow me to cross reference HR with virtual power and RPE.

    BTW, that LHR test is usually better done on an indoor trainer as it's easier to maintain the effort, unless you know. nice long flat(ish) circuit where you can ride uninterrupted.
