Threshold Part 4 - Other Models




In Part 3's exploration of mathematical thresholds we were looking at methods of approximating a rider's power curve, which allows us to estimate maximal power for a given duration. However, that's rarely how we ride (or run, except on the flattest courses). The models discussed assume that an athlete stays at precisely the same power for the duration of their effort, but in the real world only TTers even come close. So this post will look at ways of dealing with variation.

Threshold Part 3 - Mathematical Thresholds



So far I've looked at the biochemistry behind thresholds, and evidence for whether thresholds exist (it appears they do, but not the one we all call 'threshold'!). For this post I'm going to look at some of the ways that we have tried to describe our thresholds and limits.

Combining Zwift with Sufferfest/PerfPro (or TrainerRoad)

Zwift is new and exciting, but I still reckon the last two reps of Sufferfest Revolver are as close as I'll get to a religious experience, and I'm a big fan of Perfpro's easy customisation and ability to display live graphs of geeky accessories like my Moxy SmO2 monitor. Is it possible to get the best of all worlds?

Zwift on a Budget

In the last month or so I've found myself getting into Zwift, the online cycling game. Last night I attended one of their events, where I ended up demonstrating racing in front of a large crowd (who were mostly looking the other way), and showed conclusively that turning up late to the race start with no wifi isn't a brilliant idea! (Much respect to the colleague who managed to build his computer for me in the 4 minutes before the race started and managed to get me starting only 15 seconds behind the main pack!)
A few people have been concerned about how much it might cost to run Zwift, particularly if you're going to end up leaving the computer in the garage for ease of access. So I thought I'd document my setup to show you can run it on fairly old kit.

Zoot Makai Shoes

I've been racing and training in Zoot Makai shoes since joining Team Zoot Tri Europe this season; having accumulated a fair few miles on various terrain, and races from 10K to marathon, I felt it was worth jotting down some thoughts.

Cheap solution to prevent bottle launching


I'm a big fan of XLabs and their behind-the-saddle bottle mounts; but I'm sure most people who have mounted bottles there have at some point experienced 'bottle launching'. This is at best annoying, and at worst could totally derail a long distance nutrition plan. I'm aware XLabs sell a 'Gorilla' cage which they state will prevent launching, but they're very expensive and British road surfaces are pretty ingenious in that regard.

I've always used the cheap 'Elite' cages which are available in all sorts of colours, and have a rubber tab which holds on to bottles fairly well. However, after a recent launching episode I thought I'd try something new.

Step up, 80mm nitrile rubber o-ring. (I bought them from Amazon but I'm sure you can find them elsewhere). Wrapped as per the photo, they add a bit of friction to the cage and seem to work very well - certainly no issues in a recent race where I saw quite a few cages (Gorillas included) shedding their load.

Feel free to share any other top tips in the comments!

Outlaw Triathlon 2016

After kicking off my triathlon career at IM Wales in 2011 I decided to find out what distance I suited best in 2012, by racing all of them. The Outlaw was my chosen iron-distance so I returned to it this year to see whether I've improved.
