@worldtriathlon @hugo_milner Fastest 10km in a world triathlon event? Anyone run faster?

[sean jefferson @Semjeffe]

@jasonpedersen Going out for 5k?

Shelly: What would you do against me in a 100m?
Mondo: I would beat you
Shelly: Survey says...that's a lie

@GoCiaran @_Morgan_Pearson @MattMcElroy9 Wear briefs, they are fast.

@jasonpedersen @mo_pedersen1 This is exactly what happened to me in LA marathon. My running past worked against me. I ran way too fast through 20mi, whole body locked up with 3mi to go and any downhill was a nightmare on my quads.

World Cup Triathlon in Lievin. 150 meter swim, 3k cycling and 1 kilometer run. Which current 1500m runner wins this race @macfleet1 ? My pick is OliHoare

[sean jefferson @Semjeffe]

@DavidJensen81 @Alan_Couzens Per week, the article he referenced is from elite distance runners.

@parsamsons Asking the equipment room manager for another set of track warm ups was a pain.

@davidels373 @Scienceofsport @KiddTalksNFL The Pogacar to enter F1 next season and dethrone Redbull.

@macfleet1 I think it’s time for Hayward field to step up, 105 laps of Hayward Magic.

@ORION_coaching Before people go nuts, the first part was a joke I know he meant Stapley. But the other points are legitimate questions.

My belief is a technical sport like swimming won’t gain as much of an advantage from doping. EPO won’t improve poor technique.

@ORION_coaching Who is “Max Stanley” and what stats, data or authority does he have to back up this opinion?

If triathlon was composed of the 3 dirtiest sports, which it’s not, Why is it not even on this list?

How are triathletes avoiding ADRV’s when athletics and cycling can’t?

@parsamsons Lukas won the 2011 Triathlon World Championships Junior race 5 weeks before racing Nutty. I don’t think he ever recommitted himself to running after that win, he went pro before the conference meet that season.

@BrentNieter @SaraHall3 I grew up in Palm Beach, FL.

[sean jefferson @Semjeffe]

@TheRealMerb @jgault13 I disagree, to increase quality he could increase quota for countries in certain events. For example give US 6 entries in men’s and women’s 100m. Give Kenya 6 entries in 1500-10k. This could be done on a country ranking system per event.

@slydawg1853 Enjoy! I had a blast when they came to Boulder.

@nickwillis @kelrock1977 @rusty_woods Hard to tell, but the GC guys save a lot of energy sitting behind their teammates for 98% of the race.
