Physical effect of cycling the Deloitte Ride Across Britain

WARNING :  Some readers may find the images at the end of this post upsetting as they show the results of my crashes on Day 1 and Day 5.  You have been warned!

I knew that cycling over 100 miles a day for nine days with no break would be very tough and I had wanted to make sure that I would enjoy the experience and not just “get through it”.  I had worked with Lawrence Cronk at Enduraprep on my general fitness for several years and when I signed up for the Deloitte Ride Across Britain, Lawrence started me on a specific training regime to improve my endurance and cycling specific fitness in particular.  As Lawrence takes part in full distance Ironmans and coaches other people for triathlons so he knows what is required.

The training started in earnest in October/November 2017 and my blog Two Months To Go – Training Review sets out what I had done to June 2018, basically three indoor sessions a week and one or two outdoor rides at the weekend.

In November 2017 I weighed in at a pretty hefty 94 kg (188 cm tall) and just before the ride I was down to 85 kg.  My fitness levels had also improved dramatically as measured by my Functional Threshold Power tests.

After getting home from the ride I was surprised to find that I weighed 86 kg as I felt thinner based on the “belt notch” test.  However, closer inspection of the “clever” scales showed an increase in muscle mass and a decrease in body fat percentage from 20% to 15%, an astounding decrease of 25% over the course of 9 days!  It showed that despite eating a lot during the event, my body ended up eating into my fat reserves to keep going.

The fitness stats on Training Peaks also showed how hard I worked during the ride.  The stats show that I was far too enthusiastic on Days 1, 2 and 3 and paid for it on the later days when my output in terms of power decreased although the intensity required to ride stayed pretty constant – in effect I was working just as hard for less results!  I think I also realised my error and consciously tried to keep my power output low when I wasn’t having to climb very steep steep hills.  I had found Day 4, meant to be an “easy” day particularly hard.

I was also surprised that my maximum heart rate for each day reduced by 20 beats per minute over the course of the 8 days (from 181 on Day 1 to 163 on Day 8) despite the fact that Day 8 had The Lecht climb with a gradient of 28%!  I’m ignoring Day 9 as the gale force tail wind made things relatively easy – thank goodness!

On the graph above, the pink line shows my fatigue increasing dramatically as the ride went on.  The blue line shows my fitness while the the yellow line shows my form.  I’ll be on top form for an event at the beginning of October! The form line shows how I was “ready” for the ride as well.

As an addendum to my fitness, I did a Functional Threshold Power test 10 days after getting back from the ride. My FTP has increased to 268 compared to 261 in the week before the ride, so I’m much fitter having done RAB.

Now for the “nasty” bit and photos of the results of my crash on Day 1 after 40 miles at Truro which I then aggravated with the crash on the railway crossing on Day 5.  I didn’t take a photo of the initial damage on Day 1 as the medical team immediately slapped a bandage on it when I when to see them after having a shower at Oakhampton.  The rest you can see for yourselves.

In answer to the question “Does it hurt?”, of course it blooming well does!  I’m now on a course of antibiotics to beat the infection and going back to see the doctor next Monday to make sure it is healing.  I have a plentiful supply of dressings but may opt not to wear a suit to work.  I don’t think possible seepage through the bandage and wool suits will mix!

Final week of training before the Ride

I am now entering the final week of training before starting the Deloitte Ride Across Britain on 8 September.  This weekend saw me do two rides of over 5 hours, although not on consecutive days as originally planned due to the appalling weather on Sunday.  I know some of my fellow Deloitte RAB participants did brave the wind and rain – good for them.  I chose the indoor option to avoid catching a head cold or even worse crashing the bike!

My ride on Saturday was meant to be “flat/rolling” and I still managed 1,931 m of climbing in about 86 miles of riding.  The ride today was “three climbs” and I did 2,134m of climbing in 88 miles of riding but in a longer time, probably due to the length of the climbs.

The ride today can be seen on on Relive map here – lots of hairpins on the climbs and descents!  The benefits of living in South Wales.  I was lucky with the weather as there were a few spots of rain but I managed to miss all but one heavy rain shower.  The rain did make some of the early descents a bit tricky and I certainly picked up more speed later on in the ride when the road dried out.

On the Saturday ride, I revisited some of my training loops round the Vale of Glamorgan and here is the latest “season” photo from Merthyr Mawr img_0742.jpg– all the rain in the last week has raised the river levels considerably since mid July when there was just a trickle.  It is also amazing how much a little rain changes the grass from yellow to green!

The end of the serious training has also enabled me to take stock of how far I have come since I started training seriously for the ride last November.  The biggest change is the weight loss, down from 94 kg (perhaps even more) to 85kg (13.5 stone in “old money”, a loss of around 1.5 stone).  I’m sure the weight loss would have been greater if I’d been more disciplined with the diet, however, I’m now the lightest I’ve been since starting work in Cardiff 15 years ago.  It has made a huge difference to the speed at which I go up the hills!

My fitness levels have also improved dramatically.  The Training Peaks fitness level has increased from 60 to 108, my Functional Threshold Power (a test used by cyclists to measure their power output) has increased from 239  to 261 watts and my resting heart rate is now in the low 40s.  I don’t think there is much more I could do to prepare physically for the challenge ahead.  I have to thank my coach, Lawrence Cronk at Enduraprep, for the training plans and pushing me on in the training.

I think the most difficult part will be the mental side of getting up shortly after 5am each day and start cycling 110 miles a day for 9 consecutive days to complete the 980 mile distance from Land’s End to John O’Groats.  I’m sure once I’ve got over the initial 10 miles I’ll be fine – this was the case today when there was a lot of procrastination before setting out.  The thought of everyone who has very kindly sponsored me to support the work of Dementia UK will give me all the motivation I need – I will not want to let you down!
