Team Accelerate member and On athlete Andy Shelton has been putting the new On Running Cloudboom through its paces.
Heel-toe drop: 9mm
Weight: 225g
Best use: Road Racing
Price: £170
The CloudBoom is On running’s adventure into the world of carbon infused running shoes, The CloudBoom has been engineered for fast marathons and road races.

Straight out of the box
When you pick up the shoe, you immediately feel how light it is compared to On’s other long-distance, race based CloudFlow and CloudSurfer running shoes.
The CloudBoom is very distinctive. Many design hours and fine-tuned running tech have gone into creating an absolutely gorgeous shoe. As On say – this is definitely “Swiss engineering at its finest”
You will be pleased to know that the CloudBoom retain On’s signature cloud shaped sole. However, it is certainly fair to say that aesthetically they are rather different to On’s regular shoes. It is the only time I have seen a shoe and said “it looks fast”
When you push off for your first run, you appreciate Ons carbon infused speedboard. This flexible, but not pure carbon, speedboard offers a good balance of both rigidity and robustness, so every
step feels light, fast, and responsive.
The materials used in the CloudsBoom tick every box. The upper consists of super quality, ultra-thin and breathable engineered mesh to keep the weight down. The forefoot is reinforced so it can handle all types of turns.
The CloudBoom is well cushioned yet very different mainly due to the exciting set-up of the sole. Side on you can clearly see the different structural layers. In between the top section of the sole, (which incorporates On’s Helion™ foam to aid comfort), and On’s fabled CloudTech™, sits the carbon infused speedboard.
The rubber sole is noticeably different from On’s normal road shoe models. This is to offer you, the runner, enhanced traction and grip in the wet – which could provide increased acceleration and confidence. On have also made some other tiny changes such as the shorter tongue, which minimises weight and shows how On are trying to maximise the efficiency of this shoe.
Compared to the other carbon shoes on the market, the On CloudBoom is considerably more subtle, definitely not shouting out to everyone that you are out to PB, more like running in stealth mode.
After 3 weeks of testing (70 miles)

the new On CloudBoom I have noticed a few things; they are comfortable and super smooth to run in, the shoe is really snappy and provides a quick return for maximum cadence, and definitely has been easier on my legs, calves and achilles, which, for long distance runners, is a must. These shoes basically worked with my body and responded to the amount of effort I put into them. I tried them over a long distance, intervals and mixed pace runs. They responded superbly and I got the extra kick when I needed it. They are definitely now my favorite On running shoe, and most certainly a game changer!

My opinion
the CloudBoom is best suited to the road running for a decent amount of training miles. A superfast, comfy shoe to take on road races from 5km to Marathon distance and to get your desired PB’s.
Fantastic new On running shoe added to the On shoe family.
*I have put the cost in both categories as a carbon infused shoe it’s relatively cheap compared to others, but for the casual runner, it’s expensive and may not be for them.

Week 8 and have not been outside the gate. This not because of Coronavirus phobia but because my wife is on the government extremely vulnerable list for the virus.
I do not have dumbbells or a yoga mat but what I do have is a furnished house and a garden. You do not need a gym to keep fit. So how have I managed?
Daily routine consists of 10-minute workout in private in the bedroom. Starts with spinal stretches. Can nearly touch my toes. Hamstrings are held taut and stretched by placing a foot on a chair. Hips are swung without shoulders moving. Shoulders swung with hips held firm. Dressing table is pressed into action for bicep and triceps dips. Even though it is only 08.30 am out comes the gin bottle. A litre bottle of Tanqueray Gin weighs 1.602kg. (at the start of the week.) Useful for developing upper body strength, mainly bicep curls. The bedroom rug doubles up as a yoga mat for sit ups. 
Walking around the garden I can resist re-enacting a scene from John Cleese the Ministry of Funny Walks sketches. High kick walk. Then opening and closing the hip gate as I progress down the path. Amuses the neighbours whom I am sure wonder if I am losing sanity as isolation continues. To add to their entertainment, I run a mile around the garden each night. 30 to 40 m of ascent depending on route. So many twists and turns that it takes at least 22 minutes of strenuous effort. PB 20.05 all comers welcome after lockdown is over.

Add to this routine Sunday I act as house fairy. Hoovering is a brilliant exercise. Use those Abdominal muscles. Move furniture, Weight lift on the stairs. Put in the occasional star jump. Bee bop to music whatever but the job gets done. Windows are washed, requiring step aerobics as well as upper body work out. Even watching TV or working at the computer induces the odd chair squat

Twice weekly 2 kg of bread dough are kneaded. Shoulder ache after this 20-minute workout.
The outdoor gym AKA the Garden then becomes my focus of activity most days. A wealth of equipment here. Electric mower that needs pushing. Hedge cutter waiting to be used. Barrows of compost to be shovelled and lifted. Land drains to be dug up, unblocked, and then relayed. Essential tree surgery using hand saw and loppers from the top of a ladder. Seemed as if every muscle group was used as I soaked my aching body in the bath.
I just have strength left for the final exercise of the day. To lift and then extract cork from 1.134kg bottle of Chardonnay.
Hopefully, lockdown will finish soon, and I can resume my normal restful exercise routine namely a daily 2-mile walk, The Over Fifties Running Group on Fridays, and Park Runs Saturday. Despite all the above or perhaps because of it time flies past and I feel FIT and EXHAUSTED
Thanks to Laura Hogg for this amazing buzz post, she is a sports therapist for the Accelerate Performance Centre and a keen runner and cyclist. Hear some of her thoughts on the benafits of regular movement.
Like most at the moment, I am incredibly grateful that outdoor exercise is considered essential activity. It’s hard to imagine life without it. But even while we have this luxury, movement matters the rest of the time for the health of our mind, joints, muscles and cells.
Personally, I’m hoping not to slip into sedentary habits whilst working and living from home – even whilst we can run. It’s tempting to think an hour or so of exercise is enough to offset 8 hours of loafing around, but unfortunately not.
Movement Matters is the name of a book by my favourite biomechanist-writer Katy Bowman (I don’t actually know any others). I’ve enjoyed her writing for a while – it’s fascinating and entertaining. Bowman is best known for her book Move Your DNA and her online blog Nutritious Movement.
We might be used to going out of the house for our exercise, and be starting to feel frustrated with a lack of it. But movement more, and more important, than exercise. In Move Your DNA, Bowman explains why your heart and cells needs your body to keep moving in a variety of ways:
- Blood isn’t only pumped round the body by the heart. Muscles have an important role to play too. The heart pumps blood into arteries, but it is working muscle that draws it into the capillaries through the opened walls of the arterioles (also muscle). By moving, our muscles deliver blood to the tissue that needs it.
- This blood doesn’t go everywhere in the body though, just where it is needed for the activity. Regular exercise doesn’t guarantee good blood flow to the cells in all of your muscles, only those that are working. For our blood to nourish all of our tissues, we must move often and in varied ways.
- When we are sedentary, our muscles don’t help our heart. The heart must do all of the pumping by itself – possibly for hours at a time. So by jumping up from a sedentary afternoon at the laptop and heading out for a run, we are asking the heart to work harder than we might realise.
- Our cells adapt to the way we use our body. Our body responds to the load created by our movement (or lack of it) to create tiny changes in our cells. By standing, walking or running, we create load on our body as it carries our weight. That’s why the bone density of runners tends to be higher than that of cyclists, because runners bodies support their own weight, creating more of a load on the body than sitting on a bike.
I’ve seen lots of ideas recently about how those with spare time in isolation could use it to paint the spare room and read all of the books. But this is an anxious time, made harder for lots of us because our outside hours are limited. Who needs pressure to emerge from isolation with a headstand, a massive brain and a shiny house?
There is loads of moving to do at home, such as standing up from the sofa (that’s a squat, right?!), following pets round the house for attention, hunting for the remote control…
Personally, I’m just trying to not sit for too long, especially on a chair. If I sit on the floor I end up in loads of different and awkward positions, but at least I’m moving!

Stay safe everyone!
