Cyclists with a "Running" Problem

I can't find Tete Dijana's stats but according to Strava, Piet Wiersma (GARMIN FR955) covered 86.23km whilst Gerda Steyn (COROS PACE 2) covered 88.48km. These individuals had the best available lines to pick, yet the distances don't match anything official.

My wife and I both run using gps watches, both Polar but slightly different models... We can go for a 4 km jog together running side by side the whole way and never get the same speed or distance.

The polar running training programs that you can download onto your watch work off time in a zone and heart rate. For example I'm using a polar training program for a 21k race and all the training is according to my HR zones and time spent in a particular zone, no distance involved.

Don't mention the HR readings... wrist optical vs chest strap...that's another can of worms

Honestly, what a load of click bait. Must we all run around with wheels so we know how far we have gone? They also don't mention was it gps, gps with glonass, gps with glonass and galileo? etc etc etc, there are factors in your setting that can affect it as well. Is your watch recording every second or did you need to scrimp on battery and it is recording every 3 or 5 seconds?

The horizontal error in a gps is so small it will not affect your pacing strategy to a point where it will affect your performance, you have also spent month training with that same error so you really can't feel the difference between what a gps measures and a jones counter measures. If your gps over read for all your training runs and over reads for a race, the ratio of distance in training to racing is still similar.

Analysis Paralysis. An affliction affecting many.

I'm curious, how big is the difference?

The wrist base HR is pretty good these days, on my Polar and the wife's Apple watch at least.  I still however always use my H10 chest strap when training,

I'm so used to it that it will feel weird without it .... 🤪

If your gps over read for all your training runs and over reads for a race, the ratio of distance in training to racing is still similar.

Please also remember a jones counter is accurate for the exact route that the wheel follows. Now when the road is 8-16m wide like for comrades, just going back and forth across the road and to the sides for water, to throw away rubbish, high 5 a friend etc will add more distance so a jones counter is great, if you know the exact route it took and follow it exactly. Again not needed- the error margin is so minimal it makes no difference to your race. Like I said before you should not be cutting it fine for goals and cutoffs, you need to leave some error margin. Want to run a 40min 10km, aim for a 38min 10km. If you are planning to cross the comrades finish line in the last 5 mins you actually shouldn't even bother starting, if you going to do something, do it properly.

To be fair, quite a few of their videos has the taste of "buy this crypto, not that one to become a millionaire" level of clickbait. . . .

Same here for my wife and myself, exactly the same Garmin FR245, we try and start everything at exactly the same time, from starting to acquire satellites to actually starting the run. Always out by a few meters, and kilometer marks sound off much differently.

Range director clearly not taking any accountability (ALthough I do believe you have more than enough time to finish especially with the 12 hour cut off)

Absolute Disgrace by the CMA. Think the whole board forgot what the race is all about. Why don't they get previous runners like Fordyce or Nic Bester to serve on the board. I would be ashamed if I was Rowan James right now.. I guess money talks.

Agreed think Fordyce would do a great Job (Bester aswell but don't think he would leave his Nedbank coaching)

The replies from Rowan are a joke looks like a high shcool child wrote the replies not the race director.

I was actually expecting  the "yo momma" insults to appear somewhere along the line

And here I was planning to do the event next year. Maybe I should reconsider.

An absolute shocker. Not just his response but also a number of the other issues raised, which point right back to him as the RD. Really an unfairly poor reflection on the Comrades team and should be taken to task.

a wrist based gps has a lot of tradeoffs going into it's design. acceptable accuracy is one of them.

2.5% ok this is 2010 but the physics haven't changed.

He could (should) lose his job over this. There are clear issues and if this is his response that he knows will go public, then imagine what he is saying behind closed doors.

Quite sad to see those responses to fair questions. Someone in the position of Race Director should do better.
