Banister Impulse Model
Following establishing some formulas for replacing TSS I wanted to see why the decay parameters were chosen as 42 and 7 and why these numbers were considered to have a unit of days. I could never see what 42 days represented and hence my establishing a half life equivalent which seemed to have more meaning.
The modelling of Training Stress over time comes from Banister’s Training Impulse Model (reference required) which is:
TRAINING STRESS BALANCE
This is the commonly used method for modelling your fitness and fatigue. It works on the basis that your current fitness is the total of all training done to date with a decay factor to reflect that the impact of a session on current fitness decays with time. Similarly your fatigue is impacted by all training done with a decay factor applied. Training Stress Balance (or form) is just the difference between them. Continue reading
7:08:11 – 46th Overall, 32nd Mens
A little bit of background to this year so far will help put this race in context. I’d entered both races on the assumption that I’m normally very fit at this time of year. This would be particularly the case this year as I’d entered London Marathon so I’d have done a lot of running and then the race was only a couple of weeks after our EverydayTraining Lanzarote Camp. However this ended up being far from the truth. Continue reading
2:21:11 – 6th Mixed, 16th overall.
At the race breifing a couple of hours before the start we were told that tow lines would not be allowed until the second swim as everyone would be too close and would get tangled up. This certainly helped Rachel lighten the load before the race as she told me she was now “bricking herself”. On the walk back to get ready we agreed that she should just hold my ankle with one hand and swim one handed. Continue reading
My Eddington number calculation started out in 2008 within my spreadsheet based training diary. The only realistic way to do it then was to have a list of the numbers I was tracking and a cell that calculated how many days I’d exceeded the number. It didn’t take much to calculate each number manually and from there the cell would be flagged if it was no longer the number. When only tracking basic numbers (e.g. miles for each of bike and run) this is not too cumbersome an approach. Continue reading
3:47:59 – 1st Mixed Pair, 4th overall
~ 14.5k run, 6.5k swim
Retained our title ;o) Continue reading
118km, 5:47:17, 3,129m ascent, 4 cols, 100 done !!
We didn’t wake to rain but we did to low cloud. It was very nice weather to ride in as it was a little cold and a very slight drizzle as we rode as a nice calm group up the Hourquette d’Anzican. Like all of todays route I’ve ridden it numerous times and though we climbed 700m in about 17km it never quite feels like a climb. The 10 of us rode at a very comfortable pace two up rising in to the cloud. Ian was at the top with the sun almost coming through.
99km, 4:59:55, 3,163m ascent, 5 cols, 96 total
Ian and Julie had to leave early as the Col D’Aubisque was closed from 8am. We had to drop bags by 6:40am and they were off by 6:50. The rest of us had breakfast at 7:15 and even though it was a shorter day we had nothing better to do than get going.
136km, 6:37:43, 3,322m ascent, 16 cols, 91 cols total
We woke to pouring rain which matched Ian’s comment that they’d never done todays climb in clear weather. My local weather man, Marc had his own forecast and he’s never let me down. The rain would stop at 8:30am – our scheduled start time.
120km, 5:32:38, 2,602m ascent, 10 cols, 75 cols total
Most important things first. It’s the end of the week and the first time since 2011 I’ve contributed to my life to day weekly total hours Eddington number !! This week has been 47 hours – all biking.
