Nike Human Race - TFR's first 10k!!

Yes, yesterday TFR entered himself into his first 10k run - the Nike Human Race based at Wembley.

I'm not sure how much you've read about the Nike Human Race, but certainly the various forumites at Runner's World were not particularly enthusiastic.

Without wanting to rehash it all here, many people were complaining about the fact that it was (a) too expensive for what it was, (b) based in Wembley, so not easy for everyone to get to, (c) a twisty track, (d) based in Wembley, which is not the prettiest run and (e) not particularly well organised to the extent that Nike were unable to give anyone a definite start time.

On the day, Nike's (dis)organisation appeared to be even worse. The poor runners in Waves 1 and 2 were herded onto the pitch, where they stood from before 6pm until around 7.30pm when the first waves headed out (while the heavens were opening up on them through the open Wembley roof). All of this came after two support acts - Pendulum and Moby - who only a portion of the runners were interested in. In my view, these acts were entirely irrelevant but even worse than that, they made the event worse by delaying the start...

Anyway, I was in Wave 4, so started running at about 8.20pm (this, despite having to be inside the stadium well before 6pm).

But once the race was underway, things were actually rather good. I worked hard to keep my heart rate down (so in other words, worked hard at not working hard, ha ha!) and other than blisters from about 7k, had a really great time. The rain probably helped to keep everything cool, and certainly kept the dust down from what is the Wembley building site. The fact that it was dark made the floodlit Wembley stadium even more dramatic (as well as hid some of the less interesting parts of the industrial estate we were running around). And the marshalls, some of which had been there since 4pm, were continually shouting encouragement and clapping - in fact the marshalls were the best part of the event.

As I'd started off relatively slowly, it meant that I was able to pass a bunch of people throughout all of the 10k, which was a very nice feeling and probably contributed to my thoroughly enjoying the race (once it had started).

And my time? 1 hour 5 mins 20 seconds - not bad for my first 10k I think... At least I was happy with it.

Will I do more 10k's? Absolutely - but will probably aim for the larger ones like this where there is more of an 'atmosphere' and more people who are my standard (or worse, hopefully!)

Will I do another Nike event? That depends. I think that the whole concept of this event was completely misguided and I'll be a little more suspect of any future Nike event. Certainly, if they can't tell me when I'll be starting (to withing 10/15 minutes) or think that locking people up in a stadium for three hours before they can run is an acceptable way of organising a race, I'll be going elsewhere...

In any event, I'll be wearing my "I raced the world" finisher's T-shirt with pride!

Rapid weight loss

A bit of a funny week this has been... But a good one!

When TFR weighed in before the Wimbledon Common Time Trial 5k, he weighed around 100 kg (Saturday 23rd).

His WCTT run performance was dismal. Although he felt great around the whole course, and overtook a few people on each lap, when the clock finally stopped, it was very much the wrong side of 30 minutes... He was at a complete loss to understand why, although a bit of analysis on the Garmin Training Center software showed why. When compared with other (faster) runs around Wimbledon Common, it became clear that the run felt easy because it WAS easy... Basically, he didn't push himself hard enough - his heart rate was a good 5 beats per minute lower for the duration of the run...

So anyway, 100 kg on the Saturday.

Then his weight started to drop throughout the week, so that only 6 days later, he is weighing 3 kg less!!

So what might be the reasons for this?

1) Venom Hyperdrive!!! Actually, no. He hasn't been taking VH for a long time (and never really took it consistently... He has a stressful enough job without adding further anxiety with caffeine pills and other 'metabolic enhancers' in VH

2) Exercise? Well he's done a bit more this week than normally - a 1.5 hour bike ride (around 20 miles) on Monday, and a 30 minute run around Kensington Gardens on Wednesday evening

3) Diet? Not sure - although his lunch has become healthier (the Pret a Manger chicken salad rather than a big toasted sandwich) he has still been having a few drinks in the evening. In fact, yesterday's intake consisted of the salad, 1.5 bags of crisps, a few cans of diet coke, two slices of ryvita with smoked salmon, some shepherd's pie and two glasses of champagne. Not obvious diet food!!

So he's at a bit of a loss to explain why this is happening, but it has given him the motivation to watch what he eats more closely. In fact, he was in the office canteen this morning, where every friday they provide free sausage and bacon baguettes (and they're good!) but he went for the muesli instead.

The good thing is that he'll be hauling around 3kg less in this weekend's Nike 10k race.

Talking of which, I must be going so I can pick up my race pack!

The Fat Runner is dead...

...but still running...

Well that's what his Garmin Forerunner 305 is saying.

Before he bought the Forerunner, he researched a bunch of running forums, including the Runner's World forum to see what other runners were saying about the Forerunner 305.

Most runners seemed to be complementary about its features - fast GPS lock-on to satellites, able to track satellites while running in the woods, virtual trainer feature etc. Many of the negatives seemed to be around two things. Firstly, one of the metal contacts seems to go black, stopping the forerunner connecting to a PC and also stopping it from charging. Secondly, some people felt that the Forerunner battery didn't get close to matching the 10 hours battery life promised in the specification.

TFR decided to take a risk on the first concern, and realised that the second concern would be unlikely to be a concern for him - 10 hours of exercise in one go? He's not The Fat Ironman!!

But TFR has a third issue with the forerunner 305 - and that is the life of the battery in the heart rate monitor chest strap. Garmin promises that it will last 3 years, used 1 hour per day - in other words around 1200 hours. TFR, however, has had to replace the battery three times in two years - and this is running on average (perhaps) a few hours per week. So he's getting at most 100 hours out of a battery.

Hence the title of this post. According the his Forerunner, TFR now has no heart rate...

Does anyone else find the same? Perhaps the strap "switches itself on" even when it's not being worn? I'll contact Garmin to see if they have any idea...

The Fat Runner does Fartlek

Fartlek - no sniggering in the back please...

As promised in his Friday night post, The Fat Runner got out into Kensington Gardens on Saturday morning for a 5k run (31:30 or so) and then again on Sunday morning for the same run (31:00 or so).

For the Sunday run, TFR decided to do some Fartlek - mainly because he didn't think he'd be able to keep running for the whole 5k. As regular readers know, he hasn't been able to train as consistently as he'd like given his Plantar Fasciitis injury.

So what is Fartlek? Well Fartlek is Swedish for "Speed play" and it is basically a relatively unstructured session with a mix of running speeds - from walk up to sprint.

TFR ran for around 15 mins before beginning his speed play session - probably roughly a quarter walking, a quarter slow jog, a quarter running, and then a quarter at around 400m pace...

And the interesting thing is, even with the amount of walking, the total time for the run was less than the day before.

Of course, this might just be part of TFR getting used to running again after his plantar fasciitis rehabilitation, or it could mean that this is the fastest way for him to run...

If nothing else, Fartlek certainly makes the training session more interesting, and they say that it increases fitness more quickly.

The summary - TFR is going to be building Fartlek into at least half of his training sessions going forward...

Win some, lose some

As you know, The Fat Runner had a surprise last week - that his heart rate when running was able to get up to 196bpm - much higher than predicted by the many maximum heart rate formulae. This appears to prove one thing - that the maximum heart rate formulae are entirely useless when trying to understand the level at which you should be exercising.

So armed with this new information, as well as a quick look at the Runners World website to understand the ranges he should be working in, TFR headed out for the weekly Wimbledon Common Time Trial.

The Runners World website suggested that someone with a resting heart rate of 60bpm, and a maximum of 196bpm, should be running a 10k at 176-182bpm.

This seemed rather rapid, so TFR backed off a little from these figures, aiming for a heart rate of around 170-175bpm on the first lap and 175-180bpm on the second lap.

Well it seems to have gone rather well! He ran what felt like a very comfortable first lap and then was able to push a bit harder in the second lap (instead of hanging on desperately which is what he normally does).

He'll definitely be following these heart rate guides into his next race.

Now, the final sprint....

Again, his heart rate peaked in the mid 190s (so proving that the result last week was not spurious), but unfortunately when he tried to put in a second kick for the line, one of the muscles in his hamstring gave way (an obvious rip) so we'll have to see if he turns out next week or not.

Next time you hear from TFR, he'll tell you all about hamstring strain repair!!!

Maximum heart rate research

I've oone a little research into maximum heart rates (given TFR's recent run), but the overall conclusion is that these maximum heart rate calculators are entirely useless.

So let's go through them:

Basic formula: 200-age
Londeree and Moeschberger (1982): 206.3-(0.711 x age)
Miller et al (1993): 217-(0.85 x age)
USA researchers (2007): 206.9-(0.67 x age)
UK reseachers (2007): 202-(0.55 x age) for male athletes

Now applying each of these formulae for maximum heart rate to TFR's age gives a maximum heart rate of 182 (Londeree and Moeschberger) to 188 (Miller et al). Nothing like the 196 that TFR recorded on his latest run.

By the way, TFR has downloaded his heart rate from his Garmin Forerunner 305 to check whether this was a spike reading or not. The sad reading is that it wasn't a spike - his heart rate gradually crept up to this level as he sprinted for the finish...

In some ways, however, this is good news!

Now that TFR knows that his maximum heart rate is very different to that predicted by a formula, he can work out what his real heart rate training areas should be! More on that in the next post

Can his heart rate really be so high?

TFR ran again last Saturday for the ever-excellent Wimbledon Common time trial.

He also took a friend along with him - a friend who is much fitter than TFR and runs marathons in 3hrs 15, so he wanted to put on a good show, and hopefully beat his previous record of 29mins 40 seconds.

He had been running relatively hard throughout most of the race - running between 170 and 180 beats per minute, which is rather high against most of the normal criteria using the calculated maximum heart rate for a 34 year old of 186 beats per minute (the normal calculation is 220 minus age).

For the last 200-300 metres, however, TFR sprinted as hard as he could. When he got to look at his Garmin Forerunner after the race, he was surprised to see that his heart rate had reached 196bpm - way above his theoretical maximum.

This is going to have implications on how he trains - more on this in the next post!

Heartbeat

Not an old Pet Shop Boys song, but TFR's heart rate chart from his run at the weekend. Do you remember me telling you that he thought he had gone off too quickly and that probably caused him to be slower than he was hoping for? Well he's downloaded his heart rate data from his forerunner, and the chart below says it all - most of the time he was above 175bpm, and at the end he got up to 192bpm!! So clearly the 220 minus age formula (for calculating maximum heart rate) does not work for him - it's been some time since he was even near 28 years old...

Running music

When The Fat Runner started running, he used to do it without music. Since then, he has seen the light (so to speak) and started listening on his runs.

Initially, he used to listen to standard podcasts, either comedy or news or business. It enabled him to focus on something else other than the run, which seemed to work for him.

However, he always wondered how he could get some good music on his ipod - ideally a long mix which would just keep playing throughout his run. Well obviously he could buy some tracks from iTunes, but he's too tight for that.

So after a little searching, he found some podcasts with pre-mixed music and a minimum of talking, which he is now (or at least was) listening to on his runs.

The first ones are just general kind of 'music with a beat' mixes, but are actually quite good:

• Beatport.com burners
• Radio 538: Tiesto's club life podcast

The next one is specifically designed for working out to, and has a nice website to go along with it!

• fitPod.com: fitMix Archives

TFR's favourite, however, is actually a podcast which has published a set of hour-long mixes, all recorded with different BPMs - and the BPMs are included in the title so you know exactly what speed of music you are listening to:

• PodRunner

Now TFR has heard that running with higher BPM music can be a way to help your legs turnover faster, and therefore create some more speed. Perhaps this is true for elite athletes, but right now TFR's leg speed is more limited by the fact that when he increases leg speed, his heart rate goes up and he hits the limit he has set on his Forerunner.

But right now, by picking a song with a BPM which is close to his typical running speed (which is about 155 steps per minute) he can run, trying to keep time to the music, which just adds a little bit of a game to his workout, and means he doesn't hit the limit on his Forerunner quite so many times.

Try it out!
