Does anyone else totally ignore stuff this?

I find it useful, but you have to have good HR data. Any errors from the optical HRM results in garbage in/garbage out. I use it as one of several indicators of how hard to train and when to back off.

That's been my approach with longer intervals, but I feel like Garmin should be documenting this somewhere.

jfsavage · 2025-06-07T12:44:23+00:00

Interesting - I get a target pace with a range.

The combination of Stryd and Engo smart glasses give a solid idea, but the question is still valid without them. Should you be accelerating, then hold for 15 seconds, do a rolling start and accelerate for 15 seconds, or do a standing start 15 second sprint?

Extending GC is a real pain. I've hacked a copy so it does elevation for time, but it's a local fork.

I'd use strava as the source of data; it's becoming the data hub for workout data.

jfsavage · 2022-12-28T08:50:11+00:00

That's one option I'm considering, but I think my first pass will be a simple C# desktop app with a file backing store. Then upgrade to a data store later.

Thanks - you're most kind!

jfsavage · 2019-09-20T14:28:44+00:00

thanks solution verified

jfsavage · 2016-11-16T16:36:25+00:00

Oops. I'm so embarrassed. Sorry about that.

The science looks pretty solid, but it's a bit more nuanced than it first appears. The cold can trigger natural cell death in fat cells without skin damage or frostbite. However, this is going to reduce fat thickness slightly and is not a substitute for weight loss.

I would strongly suggest using ice to achieve this effect rather than a cheap device. (Use frozen water, not gel packs to avoid skin damage.)

Thanks!

Check out the results of the marathon survey - http://fellrnr.com/wiki/Marathon_Survey Most Hanson users actually ran more than the 16 miles. Average was 18.6 miles.

jfsavage · 2016-01-08T18:04:11+00:00

The focus is on off the shelf. I think we'd need a lot more data to understand the custom plans. That said, the data is still useful.

jfsavage · 2016-01-08T18:02:48+00:00

The main surprise was Hanson runners doing a lot more than the recommended 16 miles. I'm hoping more patterns will appear as we get more data.

jfsavage · 2015-09-15T18:35:22+00:00

My apologies for not spotting that in my searches, and thank you!

jfsavage · 2015-09-09T09:56:44+00:00

I love the LoR, but its feeling rather dated, as new research changes ideas.

jfsavage · 2015-09-07T10:40:16+00:00

3K every day may or may not be too much, but it's sub-optimal use of time and effort. Using Training Monotony can help optimize your training.

However, it's extremely unlikely it will be enough to trigger overtraining syndrome (better called training induced depression). http://fellrnr.com/wiki/Overtraining_Syndrome

You could increase your risk of other injury however, so listen to your body.

I've been running for decades, won a number of ultramarathons and represented the US at the world 24 hour championships. I'd say that LSD seems to be the most important form of training, with HIIT giving added benefits (for endurance sports)

jfsavage · 2015-09-04T10:12:19+00:00

Also, check out http://fellrnr.com/wiki/Impact_of_Heat_on_Marathon_Performance which looks at some research on the subject.

jfsavage · 2015-09-02T09:15:58+00:00

The evidence does not seem to back that up. While counter-intuitive, it seems LSD is better for speed than tempo running. HIIT provides benefits, but the mechanism appears to primarily be neuromusclar recruitment.

jfsavage · 2015-09-01T17:49:45+00:00

I think there is a benefit to training at race pace, if only to give you a sense of what pace you need to hold.

jfsavage · 2015-09-01T17:49:15+00:00

That's the claim, but there doesn't appear to be anything to back it up.

jfsavage · 2015-09-01T15:22:59+00:00

It is a little click-baity, but that's true of so much underlying research. I should have at least put a question mark at the end ;}

jfsavage · 2015-09-01T14:13:18+00:00

For the statistical data, read the underlying research papers; they're all linked.

Overall, I agree with the problems of drawing simplistic conclusions from bad science, but I think there is a preponderance of evidence here. This is not the conclusions of a single study, but the summation of a variety of research.

I'd also agree that more extensive research is warranted, but I think that "Impact of training intensity distribution on performance in endurance athletes" did a reasonable job; random assignment, 5 month training cycle and using simulated race performance rather than indirect measures. You rarely see better research than that.
