Metabolic Testing

Last weekend saw my first metabolic testing since January 2007 in Christchurch just before Epic Camp – it was long overdue! I did a bike test with Pete Byworth from www.vo2fortri.com – I’d highly recommend him: he knows his stuff when it comes to sports science, is a cyclist, and has done metabolic testing on something like 4000 people – age groupers and elite athletes alike. Critically, he can give you lactate threshold/anaerobic threshold (and associated power on the bike) from which you can work out where you should be training and racing. You can choose to test on a bike or on the treadmill. The results were pretty much in line with what I had expected, but provide a much more precise baseline from which I can retest in the future to see how everything’s going. The test also carried power data, so this means I can use my new powertap a lot more effectively! The other bonus is that unlike a test I had done quite a few years back, blood isn't taken for lactate readings, its all done by gas exchange (COs, O2 balance), so there's no sore fingers or earlobes etc! Hope this has been phased out from most testing!

We did the test at Swim For Tri’s HQ in Liverpool Street (also where I do Endless Pool sessions), but Pete also does testing in Canary Wharf at The Cycle Doctor (Kev’s place – www.cycledoctor.co.uk). Its becoming a bit of a triathlon mecca down there at Cannon Workshops in Canary Wharf with Kev’s tri/bike shop, another Swim for Tri Endless Pool and even a yoga centre. The Docklands have got it good!

Following the testing on Saturday morning, I went and joined in a local sprint tri run by tricoach and ironman addict Mike Shaw (coach and founder of www.triperformance.co.uk) down in Raynes Park – great fun, and a bit of a change to the normal. Luckily I still managed a quality long run afterwards, and topped the week off with an overdistance bike plus run on the Sunday. This week’s been more of the same, with a little consolidation on the mileage.

Here’s some photos from the testing – apologies for the low quality, but they were taken on Pete’s phone. Luckily the low quality hides the fact that I am DRIPPING with sweat! Managed to form a large lake during the course of the testing – always attractive! ;)

Ironman Coeur d'Alene

What a great event. Early start, very leisurely swim (the downside to the pro start being 35mins earlier than the mass start is the lack of feet to choose from) - I chose badly andafter the first loop, there was no group in sight ahead to bridge up to, so I just sat in and took it real easy. The bike is beautiful, and fairly challenging - its undulating through the middle section of each of the two loops and there was a headwind on the flat return which slowed it down a bit too. The Trek got tested in earnest today and it passed with flying colours. What a sweet ride! Given there were a few teething problems - I'd only managed to ride it for about 4 hours since I arrived on friday with the race set up, so there's still some tinkering to do, and i managed to knock the front derailleur on mounting so I had a grizzly sound coming out of it in the big ring for the whole 180km. Oops.

And despite nearly talking myself into the run leg yesterday (and putting shoes in T2 bag and some gels etc, 'just in case'...) I managed to control myself and only ran the first 2 miles just to cool the legs down after the ride, and get the benefits from doing the race sim. Very proud of myself for showing such self-discipline! There was a BIG part of me that wanted to carry on, but that would have defeated the point and probably ruined me! Thought I rode OK given lack of race prep and no taper (though given some time off to let the bruising go down after monday's clash with the bus/road... does that count as taper?), so thumbs up for the nice intensity training ride today. Power meter (powertap) also makes for interesting viewing - having never trained with power before, I was very interested to see the live feedback. Not looked at the detail yet, but the average was 2 watts off what I'd figured I rode at (or what I 'targeted' for the ride as normal effort). Think the variability around this might be horrendous though! Something to work on at least.

Great to meet Blake, Gabriela and Emily - and Tristan in person from Team Timex. Blake (Becker) came 10th pro, Gabriela 6th woman pro, and Emily wa 7th I think in her age group. Good day! Headed back to the finish area in a little while to watch the finishers up to Midnight... amazing stuff. Saw Mark P and Albert briefly too - they are both ANIMALS! :)
