Running Index vs Cadence

Voila' another chart, exploring if there is a relationship between cadence (leg turnover) and Running Index (hence "effectiveness" in the run).

The graph shows a certain correlation (higher cadence positively related to higher Running Index, calculated automatically by Excel), but I can not swear that it could pass a more accurate statistical study (level of confidence of the correlation, etc), because the variance at each point is in the range of +/-5 (points of RI)...






Polar Running Index in practice

the topic might be interesting only for those using the Polar PPT SW...

I can draw a balance of my 2 years of use of the RS800sd and the related SW.
It is quite interesting to see that the Polar "Running Index" is actually a good predictor of the running shape
The chart maps 2 years of use of the watch and there is a clear relationship between my ups/down, the Running Index and the actual racing performance.
The red thick line is a 20 days moving average, to see better the overall trend rathe
r than the single workouts.
I must anyway remark that obviously also the external temperature has an influence: during the summer periods, the HR is usually higher at equal pace to, so the R.I. becomes unavoidably lower.
For myself, I could draw these references:
- R.I. around 77: means Marathon time around 2h42',
- R.I around 80: Marathon in around 2h38', HM around 1h15'
- R.I. around 84: Marathon likely in 2h33'-34' (that was the prediction based on workouts and 5k race time), HM around 1h13'

I would be very interested to compare data with other runners to see if these values have an "absolute" meaning (eg: 84 means 2h34' for everyone) or specific for each individual

Yearly Summary

The year in figures
- Distance run 4080km (vs 3550 in 2007)
- Workouts around 300 (vs 280/290 in 2007)
- Km/workout: 13.6km average
(Comment: In those 10 months were I was running, I was really consitent. it is a pity that I lost 2-3 months among the different injuries)

- races: 2 victories, 5 times 2nd
- PB in 5k, 10k, HM (sic... not in Marathon), 

Overall comment:
Well, in the figures all sounds good, but I am not really satisfied. In 2007 everything went to my plans, but in 2008 most of the time I had the bad feeling of having blocked by injuries right when it was the time to harvest the fruits of my work.
With the work done during the summer I was able to reach a "higher" level, where my racing style was more based on "running to win" than "running to do my best", but at the end I could not see the outcome in cool weather.
I think that I worked too much on the endurance and neglected hill sprints, general strenght and strides/fast work. The latest injury must also be related to this... because I was losing neuromuscolar condition.

So my "action plan" for 2009 would be:
- resume running and gradually reach a mileage of 100km/week and keep it consistently until end August. Than increase a bit more to prepare for a winter marathon (ideally Fukuoka).
I will try to run the first 4 weeks only "easy" and than gradually introduce  interval training and faster workouts + strenght training.

- I still do not know how to improve my running biomechanics. The physioterapist recommeded me to use orthotics and to add a 6mm lift to my right shoe to compensate for the leg lenght difference.  But how do you accomodate 6mm lift in a shoe ???? I tried but it is very weird feeling
I may try again with ortothics  made by different materials to see if the feeling is better. Or maybe just keep going with my 3mm heel lift (as in use now).  

- dedicate more time to strenght and core training (2 hours/week, ideally)

- dedicate more time to strides and repetition training (100m/200m sprints)

- in summer, reduce the workload compared to this year because I think I was too tired. With 30C/95%rh, probably the real impact on the body is x2 of the actual distance... I will try to make more use of my treadmill. It is boring but at least you can run in a less extreme environment and avoid the huge loss of water while running outdoor.

- also for the Summer, I will focus on short intervals at varied paces. It makes no sense to run more than 1k/2k fast without rest becuase the performance horribly degrades for the heat after few minutes of hard running.
I will avoid Tempos or long intervals and try to keep "neuro-muscolar" fresh. For a specific endurance period, the 2 months of October and November should be enough.

Race Summary 2008
- 6/Jan, HK Half Marathon Champs: 6th overall, 1h15'28". I was still tired from the 30K race of the previous Sunday so I suffered a lot, but the performance was very solid. It was a major local race, so the placement was realistic compared to my potential.

- 20/Jan, CC Half Marathon: 2nd overall. Hilly course, very good starting field, but that day I felt extremely well. I managed the effort very well, with a controlled initial 14k and than push very hard in the final 7k, leaving behind many talented runners. Felt very very confident.

- 9/March, 10k Shatin. 2nd overall, 33'36". This is the race where I have most of the regrets: we battled for the victory for 9900meters and I lost in the final kick. I did the mistake to train too much during the week, so I lacked the freshness for the final sprint...

injured. missed Krakow Marathon

-13/July: 10k. 5th overall, 35'03". Comeback race after the injury.  It was hot and I was decently satisfied with a solid performance

-17/July, 10k. 4th overall, 34'57". Very hot. I was beaten only by invited overseas runners, leaving behind most of the best local runners. So I felt confident to be able to make a good season. Time itself was disappointing because I was shooting more for a 34'30", but I was likely tired by the week.

-7/Sep, 5k mixed X-country. 2nd overall. Half disaster... I hate running in the afternoon and I did not digest the lunch properly. Maybe the first short race in my life where I had to stop to breath... the fact that I arrived anyway 2nd and improved my time by 32" with the year before was a sign of extreme fitness.

- 21/Sept, 5k hilly. 1st. Felt good and attached from the start on the big climb... the last km was painful becuase almost out of steam, but I had already a big gap

-28/Sept, 10000m track. 1st in 33'55". It felt wonderful to win a track meeting. I was very fit and lead alone the whole race. It was hot, so the time was really good

-11/Oct: 5k flat. 2nd overall in15'51". Never felt better. I did not even push 100% and come out anyway with a huge PB. Tagged with a good pack for 3k, than boosted away

injured. Missed Seoul Marathon

- 23/November. Half Marathon. 2nd overall in 1h14'28". Beaten only by a Kenyan is acceptable. This race remains a mystery: I was already crippled and missed many workouts, so I do not know why I felt good enough to run well. The achilles were not that bad and I shuffle run... so in retrospection was really a great race (maybe worthy of a 1h13' or less in ideal conditions)

-7/December: Singapore Marathon. crawled to the finish line in 2h57'.  It will be a souvenir for my older years: selected by HKA to run in their official team. VIP treatment all the way. It was a pity that my tendons lasted for 30k only; I wanted to finish anyway, but those 12k were of extreme pain...

Christmas

MERRY CHRISTMAS !!

No snow here... temperature around 23C at noon. I had troubles to explain to my daughter that we could not build a snowman and that Santa would not able to come with a sled

For my tendons, I simply threw the sponge: it was crazy to hope in some miraculous recovery. More running would have only make it a chronic tendinitis. In the morning I could barely walk up the stairs.
So I will stop running until I am pain-free and I can resume in a appropriate way.

Unfortunately, here there is only 1 and only running season (from October to March), so I will miss out completely the whole season. Very likely I must already think that my next serious race might be not earlier than 10 months from now... a sad perspective for a competitive animal like myself, but this is the reality.
I trained all Summer basically for nothing... LOL...and another summer ahead
In the next post, I will analyze the year in retrospetive

Wk 51 summary

- 16 Km in 2 workouts

not much to say... the tendons are painful whenever I run. I am trying different combinations of shoes, heel lift, whatever to see if it might improve.
My most ardent wish is to gradually improve in order to run the CC Marathon on January 18th.
But the most likely scenario is that I hang the shoes until the pain is gone, so that sometime next year I can resume running in a proper way.
It is a real pity because now is the best period of the year for running. The weather is perfect, dry and around 15C.

I scouted the web for suggestions on the treatment of the tendinitis and you can find the most disparate opinions/suggestions:
- stop running vs run anyway in reduced volume
- use heel lift vs no using it
- eccentric stretching vs no stretching
- use cushioned shoes vs use flat

2 very authoritative sources like Dr Pribut's running injuries website and the sportinjurybullettin give almost opposite advices on stretching the calf...

Wk 50 summary

0 (zero) km in 0 workouts...
everyone is very well, my wife recovers faster from delivery than myself from the marathon...
baby is very well, taken care by his little sister (who is a bit over excited)...

The nightly feed pattern seems at 20/midnight/4am, so I will try to crawl out of bet at 5am to run starting from tomorrow. I need my daily running dose...

I take the opportunity to reply to a comment from (.) (who is actually a good runner himself) about running a marathon in the heat.
I also read that article from Sportsscientists.com and, honestly speaking, I was surprise that the authors made such a plagiarism without even mentioning their obvious source...
.... because it was already everything black on white in the book "Lore of Running" (also from SA author Tim Noakes):
- Noakes reports some of his studies about running in the heat and that only smaller runners can dissipate heat well enough to sustain performance. There is even a chart with the relationship weight/temperature/maximum speed ... my weight condemns me to slow down inexorably at any temperature higher than 20C... while lighter runner (55kg) can handle up to 30C.
The subject of running in the heat covers a full chapter of this monumental book.
I am not in book reviews, but every committed runner should read it. There are countless information

- about the Wanjiru's victory, also Noakes makes a statistical studies that the "standard average winner" of Olympic marathon is not an established marathon runner, but most likely a rising star at his 3rd/4th marathon...
I am not even persuaded that Wanjiru did really trained a lot in the Japan's heat: in 2007 he barely achieved the minimum days of stay in Japan to mantain residenceship. I suppese that he did spend all summer in Kenya training, and stay in Japan mainly in Spring and Autumn to join the local racing season. Said that... he is a huge talent... we can not forget that his 10000m time at 18 years old is Junior World Record, only 20 seconds away from Bekele's open record...

incredible 48hours

I likely got the most tiring 48 hours in my life (and I guess it could be well ranked also in a worldwide classification)
Sunday 2.50am : wake-up call
Sunday 5.30am: marathon in tropical weather, limping for 12km
Sunday evening: flight back from Singapore, arrived home around mid-night. Slept only very little for different reasons
Monday whole day: work. My general conditions were ok, just very tired. Obviously my calves were totally "locked" and painful, so even for walking I must use the "shuffling" style...
Monday evening: my wife went into labour (10 days ahead of schedule), so we rushed to hospital, after having trusted our daughter to some friends
all night in delivery room. Honestly I could barely keep myself awake...
Tuesday 6.45am: our son is born !! Mom and child are extremely well
Tuesday: all day rush between hospital, collect back our daughter, etc. Big exciting day, but I was almost falling asleep while driving, avoiding an accident at the last minute. Also got a speed ticket for driving at 80kmh, while the limit at 70, but I was so numb that I traffic signs were optional at that stage.
Tuesday 9pm: collapsed into bed.
so... that's an alternative way to recover from a marathon...
now it is time to enjoy the new-born !!
