Triathlon

That one is particularly shameful. I think I am perhaps a bit bitter and twisted, as I cut my teeth in ultras 15 years ago at events which were chilled out and low-key. The canal race is still the pinnacle of how to organise a race and one that shows the true camaraderie of those who choose to go so far beyond the marathon. Helped out a few times at the 100 miles checkpoint.

If I get back to doing ultras in a few years time I will have to take a proper look at what's about and perhaps be a bit less cynical about the scene.
I'd love to be able to do the GUCR. Anyway - this site is useful Best value Ultramarathons in the UK | Climbers.net
 
Cycling directly behind another cyclist. It provides a major aerodynamic advantage (which improves the more cyclists there are in front of you), and means you spend less energy to go the same speed.
I see. So it’s only in cycling? Or is it in all of them?

I've only done one ultra, which was definitely on the lower key side - organised by a local couple and supported by volunteers from the local club. I thought it was brilliant in a lot of ways, everyone involved was so friendly and supportive. On the other had though it was largely unmarked and we spent a lot of time working out which way to go.

The next one I'm doing is with Maverick who are professionals so a bit more corporate I suppose and tbh I can put up with that for the fully marked course. I have no interest in trying to navigate it.

Not really in running. Basically when you're going through a fluid (air, water etc) it's bunching up in front of you, and it works on square law. So gets more worserer :hmm: . It doesn't give cyclists any real advantage going uphill, where they're mostly fighting their own weight. But if you're going fast... well think about how tough it is riding into a strong headwind. Stick something in front of you, travelling the same speed, and you're nicely sheltered in a little low pressure zone.

I say all of that because, if you think of water as extremely thick air, you can see that even if you're going far slower, you could still get some advantage from the same effect. I think it's something like 25% more efficient swimming behind someone.

Running, especially long distances, not nearly as much of an effect.
 
How can you effectively ban it, is what confuses me. What’s the difference between drafting and just being close behind someone?

Riders have a 10-12 meter draft zone you can’t enter unless overtaking. You have 20-25 seconds to overtake.
 
Triathlons usually have draft marshals every so often to spot check.

I would disagree in that running in a pack of 5-10 runners has some benefit, as seen at the front in an elite marathon race.
 
Resort pleased for thhed GB quartet and especially Johnny Brownlee getting a gold.

When we were at my brothers in the Yorkshire Dales a couple of weeks ago we went for a run and fuck me some of the, small, hills were brutal, and not only because I was hopelessly hungover, and it reminded me that the Brownlee brothers train in that kind of landscape
