This is in response to this video https://www.youtube.com/watch?v=XG0exWwM75U where Travis suggests a normal male beginner athlete should pull no slower than a 2:18 in their UT2 SS. Slower than that is appropriate for "prepubescent children" or "really old" people, like 70+.

"If you're a 40yr old athlete with 30-40 extra pounds, just picked up the sport, been doing this for a month or two, I'd recommend your UT2 to be around 2:06 to 2:10"
In what world?
I try to do my steady state UT2 pieces for 75 minutes at a pace where I can speak a few sentences, and feel 0 lactic buildup, monitored breathing. For me, that's 2:24. It's not hard, and is easy to maintain for that time. It's also not nothing and I feel like I worked out a little. A UT1 pace for me is between 2:10 and 2:15 depending on the day, 35 minutes. Hopefully this gives you some context for my question.
I find there is a relationship between RPE, HR, and split - I can maintain two of the three in a "reasonable" range, and the other one goes haywire. For a UT2 session:
- If I maintain RPE (like 4, normal breathing with some sweat), my split goes way down and doesn't come close to being near a 2:18. This is what I do currently, with a 2:24ish. HR around 160-168, 75 minutes.
- If I maintain a higher split (2:18 in this case) my HR goes up into the 165-175 range I'd say, and my RPE goes up to a 6, out of UT2.
- If I maintain a HR band and try to keep it between 140-150, I'm looking at a 2:30 or slower, which drives RPE down to like 2
Looking back at my data for the last month, I have a few sessions where my HR is 160 for a 2:18 and 172 for a 2:25. A 2:25 this week is 170, last week it was 150, and next week it will be 150 again. There is no correlation. This problem leaks into my UT1 sessions as well - a 2:11 pace today was an RPE 8 and HR 183 while two weeks ago it was RPE 7 and 175. I feel like I'm going backwards, almost.
So what gives? Why is there such a big discrepancy? Do I pull below a 2:18 on my UT2 and ignore RPE, or do I pull a 2:25 and ignore the general guidance?
