London Marathon: glucose monitored in fuelled race, unfuelled training and carb loading
By wearing a continuous glucose monitor, I finally get to find out whether energy gels are doing any good in my marathon races, how they compare with unfuelled training, and whether I'm doing myself any great mischief in carb loading. Skip ahead to get the comparative graph and conclusions (at 14:39) or use the chapter links to find what you're interested in.

Hacked vs standard Nike NEXT%: efficiency showdown experiment
Переглядів 4693 роки тому
In my previous video I showed how and why I hacked my Nike NEXT% race shoes. But did my mods actually make them any better? Here's the experiment to find out! See also www.wartnaby.org/running for more shoe hacks.
Nike NEXT% shoes get go-faster hacks -- hopefully

I've been chopping the heels off my running race shoes (of all brands) for years. Here I explain why, take a knife to the fabled Nike NEXT%, and try them out in a marathon. See www.wartnaby.org/running for more shoe hacks and efficiency experiments, plus my other running adventures.
The Camino in one day: ultramarathon style, Via de la Plata from Ourense to Santiago de Compostela
Переглядів 8206 років тому
Out by train, 114km back on foot, all in one day. Condensed view of whole adventure: the running, interesting sights, appendix on navigation and kit. We holidayed in Santiago de Compostela in Aug 2018. Now it's a known thing to do at least the last 100km of the Camino pilgrimage, finishing there but nobody seemed to have done the _totally_ obvious thing of running it in one day, as an ultramara...

First-person view of the whole experience, including kit details for running nerds! By a flatlander who once more trained on those multi-storey stairs... I knew I wouldn't be competitive here, so I decided to save a diary of it all. Many thanks to Borrowdale Fell Runners, esp the marshalls on the peaks!

RAF Hercules buzzing Chatsworth fountain
Переглядів 67 тис.17 років тому
This is one way to wash your windscreen... not quite sure whether the plane actually succeeded in getting wet, but it was definitely lower than the trees opposite. The fountain normally reaches 90 ft. About 4pm on 04Apr2007, at the Emperor Fountain, Chatsworth House, Derbyshire, UK. Not a scheduled event!
Brilliant video! Hats off for solo, unsupported and filming it too. Very impressive achievement, especially the car park training 👍👍👍
No word of a lie that's actually my father flying thar
Crikey!
Amazing!
Thanks, very interesting. Would it be too much trouble to ask you to repeat it for the Bob Graham Round? 😉
Ha I would be genuinely interested to see that!
This is really fascinating. I'm genuinely astounded by how relaxed you are having just run 26 miles. Well done on every aspect.
From a master influencer, I am humbled!
@@cwartcam 😂
I’m absolutely full of admiration for this solo, unsupported sublime effort! I’ve watched loads of BGR’s! Always paced and supported. This guy, trained in a car park stairwell! No mention of recce’s, although he’s obviously done his homework! Well done Mr!!! I used 22 story tower blocks in London for Ben Nevis. Featureless and horrible to train in, but needs must!!!
Thanks! And ha I dreamt of having 22 storeys to train on :-) -- good effort on Ben Nevis. I did recces but way back in 2010 on holiday, kept the GPS tracks to use for the round: www.wartnaby.org/running/bgr/bgr_for_flatlanders.htm
@@cwartcam Admirable. Did you read ‘Feet in the Clouds?’ Richard Askwith. That book changed my running trajectory😎👍🏽
@@wildernesstraining1957 yes totally, that book inspired me to do it too -- I think I might have even bought it from George Fisher in Keswick, not sure now! Cheers
Still one of the best videos on the Bob. I've written a comedy on fell running and started to post on UA-cam if you would care to check it out. Best wishes from North Lancashire.
Thanks, and best of luck with your work there!
This is a really late comment, I know. I‘ve watched this video years ago for the first time and just searched for it to watch it again. Your accomplishment is great and - as another guy here said - although it is not complying to the rules to me going solo is the true way to do such things. I have the dream to do it, too, although I don‘t think I could do it under 24 hours; but even that wouldn’t matter to me. Thanks for all the information. Especially the kit-lay-out on the table and your brief remarks on everything are priceless. Congratulations again and many thanks.
Thank you so much, and I wish you well if you go ahead and give it a go yourself!
Interesting test. I often wear a Stryd power meter/foot pod and that is 9g - so almost as much as you saved here. I never think that should make any significant difference however else might stop wearing it! In fact, even in the same size over 5 pairs of NEXT%, there is about a 9g difference between my "lightest" shoe and the "heaviest". I wonder if you ran in "full race kit" so you weren't carrying your shoes and ran for longer each time might see more of a trend. When have done similar "shoeoff" videos comparing shoes, I typically run 2-3 miles in each one at about my marathon pace. Also with the ones you cut then presume that has made them more like a zero drop shoe and some runners may prefer that and others not.
Hi Tim, I've enjoyed several of your videos! For sure yes, I made my shoes zero drop (or in fact negative drop) because I felt that was my preference, being a forefoot/midfoot striker, judging by the wear patterns on my shoes. Yet I know (see prev video) that my heel does land during mid-stance, so I really didn't know if it would be better to have that wonder-material under my heel too, or just space to let my achilles tendon stretch and rebound. Nike shoes seem to have left/right mass inequality, maybe because there's a secret compartment on one side only for their own gadget? (Remember that from Lunaracers, anyway.) I'm a bit sceptical about the Stryd power meter, because as a runner one should be minimising power at any particular pace -- i.e. maximising efficiency -- and power is totally mixed up with economy. Whereas in cycling, power is just torque x rotational speed at the cranks, and clearly more is better. I've maybe overthought mass on the foot, though I'm a proverbial 9-st weakling so I'm very conscious of carrying unnecessary weight on the feet that needs to be lifted, accelerated and decelerated with every stride -- but don't know how much it really matters. Maybe I should do an experiment with an added weight on my shoe as the only variable!
Haha, a different type of DIY :D Cool stuff! Nice video 👍
Oops just realised my spikes are Saucony (Carrera XC3), not Nike. Apologies!
Oh ourense is on via de la plata Im new and Cant understand all the rutes but love the video. Edit: i got winded looking at this but omg you are one fit man
Good job... this is on my radar for next year, just like you solo and unsupported.
The best of luck to you! There are disadvantages for sure, but a big advantage of going alone is that you can start on whatever day has the best weather (depending on how flexible your visit to the Lakes is), and at whatever time you feel ready.
This was actually my uncle he is now part of the Australian Air force
Fantastic video, all the more impressive in that you completed the round solo, well done that man. Thank you also for sharing your kit information at the end, very inspirational. Makes me feel I could also now try this solo. Congratulations!
Thanks so much, and the very best of luck if you do it! I was naieve about my route -- following paths that knowledgeable local runners would have skipped in favour of pegging it down easier grass for example. So you may find it easier!
What a brilliant, informative video and much respect to you for doing it unsupported and filming it. Im very interested to know how you train for this type of race as I live in Oxfordshire which, like Cambridge, is pretty flat. Congratulations on a brilliant run!
How kind of you to say so -- best of luck for your own adventures!
Reyt enjoyed that and respect to you for doing it unsupported... The way it should be. Thanks for sharing 👍
Cheers, much appreciated!
Just watched this with my family - really impressed. Congrats from Australia
Thanks! I was pretty wrecked by it :-)
1:07 Wow!! And great run!!
Love this! So upbeat and great running!
Very inspirational video for me as a beginner to fell racing , some time before i attempt this one if ever.
I'm fairly sure there's never been a cerveza more well-earned! Very impressive stuff (and totally mental too...)
Delightfully odd achievement.
Very impressive stuff!! Felicitaciones
can't but be really impressed by you running up and down Lion Yard car park stairs 100 times a session! Thanks for such a vivid and thoughtout video. It takes a lot of courage to try the BGR on your own but you keep smiling in all the excerpts !!
Thanks! Be warned I miscounted those steps -- it was 73 not 63, if you do the same :-)
Wow, great account of the BGR, well done mate!
Thanks!
that's a lovely course and the photo at the end was really touching x
Well done!
Hi there. I am impressed. I am also a Cambridge resident, I am interested in training for a less challenging adventure. To that end, which car park did you use? Did you run at a particular time of day when it was empty, and did people give you any grief for running up and down the stairs? I guess I should also ask if there is a best time to run up and down castle hill?
Thanks Archie! I used the Grafton East car park, which seems to be open 24/7 and is extremely quiet, so it hasn't caused any upset training there. (The Grand Arcade would be a different stor[e]y!) I do think it helps to innoculate the quads against mountain descents. I had it wrong in the video though: it's 73 not 63 steps, each ~19cm high, so ~14m vertical. Good luck with your own adventures!
Incidentally, I think that's Nicky Spinks -- outright record holder of the double Bob Graham Round -- cruising easily past me at 3:25 on the video, coming down the corridor route from Scafell Pike. Spotting her effortless progress, I did try to follow her for a while... didn't keep up of course!
Great video - amazed you could keep filming and time keeping so accurately. Great tips on food and nutrition as well. Hoping to attempt BGR first week of July. This video has made it not quite as scary. Many thanks. PS Until recently used to go to Cambridge every week with work
Really glad you enjoyed it! Believe it or not I only decided to film each peak once I'd started :-)
You did a great job. From your trip think we may be better off going to Sergeant Man before High Raise. Also the gorge on Foxes tarn route looks a bit steep - am tempted by Lords Rake. Which route did you use up Fairfield?
When I did it, Lords Rake was considered dodgy as that precarious boulder had recently fallen into place, and there was a worry it might fall further! But I think that would be better now. I was (and am) very green; for example, following the slippery footpath down to Honister -- only when I ran the Borrowdale Fell Race did I run much faster down the nice smooth grass instead, which would have saved significant time! Can't remember route up Fairfield, but the GPS log is in the page linked to in the description here. Cheers and good luck! (PS: I may be green, but I don't know why so many choose to start in the evening, immediately committing themselves to sleep deprivation -- suited me much better to leave early am when I often wake up anyway, so I felt less wrecked.)
I read about the grassy drop to Honister when I read "Feet In The Clouds" - will look out for it on the recce. Interesting point re sleep - we are aiming to start at 1am to minimise mountain time in the dark. Will probably not be working the week before so was going to try reset my body clock
thanks for posting - loved this + glad to know someone else runs 1st thing
Inspirational video and for me, running it solo but unverified is the true way. I'm 44 and thinking of a similar-style attempt next year or two before it's too late. Although I know it's not the most relevant measure: would you mind sharing what you were running a road marathon in at the time of your round? I think I've got the "steel" and mountain technique and know-how, but I just wonder if I am really fit enough to consider this...
Sorry, I think I just got the answer from one of your other vids: 2:40, ie not at all sluggish! My only hope is that I am more optimised to the terrain and ultra distance...
Hi Eddie -- really glad you enjoyed it! Yes, I've done a few marathons around 2:40 for the past few years. But as you say, it may not be too relevant to the BGR, where a lot of it isn't really running at all (too steep up/too boggy/too rocky). Best of luck!
that was my dad flying thst
Firstly very well done on your bob graham attempt. Loving the idea of hill sprints in a multi storey car park. Probably going to have to stick that in my training somewhere. :) I did a leg 3 recce the other day and i remember getting to the stop of steel fell and thinking hooly fuuck that a long way. You can just just make out the scafell's and its almost impossible to imagining running all that way.
+Andrew Macdonald Well done on the recce, hope the whole thing goes well assuming you're training for it! I'd never done anything like it before, but was amazed how you can just keep going if you don't overdo it, keep eating and drinking, and don't get cold. Though I was utterly wrecked for about 3d afterwards :-)
Hi, can I ask how much you ran and how much you power walked ?
+Mr Ski Ah, I don't think I ran anything more than the mildest uphill bits, especially as time wore on! But I did my best not to stop at all as much as possible -- walking at least while getting stuff in and out of my rucksack for example. Overall I wasn't very quick, just persistent!
+cwartcam Thank you for your speedy response. I run regular enough so with gentle runs on the flats & mild uphills/downhills I will hopefully be ok time wise (stamina depending). Will have to brush up on my map reading skills too & get some lakeland trips in for practice :)
Love the car park shots!
Pretty cool! :) I'm exhausted after watching that!
been there done it got the tee shirt respect for having done it solo unsupported and having taken the time etc to record it well done mate
Great video, takes me back to '83. Well done and all the best mate, you' ll never regret it.
An informative and inspirational video for any budding BGR folk. Also you managed to film yourself without giving off the impression that "it was all about you", as so many people manage to do, leaving a sour taste. Awesome, and fair play.
you made me smile as I've been up some of those but I never had your chirpy demeanour
Congratulation. Brilliant video and a well earned achievement!
Congratulations. Something I will certainly never do myself, but full of respect for those that have! I got tired just watching this.
Thanks -- I did feel like I'd been run over by a freight train for about 3 days afterwards!
nice and helpful video, well done on getting round.
Superb achievement, well done, and thanks for the great video.
I'm definitely going to have a go next year (time's running out, as I'll be 55). I'm currently recce-ing all the stages and I can recite from memory all the summits (it's a 'start' anyway) :-) You've taken away any excuses - I've got quite a few real hills and moors around me to train on, but your video makes it seems so easy..I'm sure if I film my attempt, my vocal soundtrack will be much more agonized ;-)
Thank you both, and good luck if and when you do it yourself!
Well done! Really helpful information and inspiring approach. I also want to do the 'unofficial' unsupported (though maybe someone in a car waiting at a couple of points) BGR - who needs certificates and witnesses to tell you you've done something! Bravo :-)
Great account and congratulations on your round!
