The Brooks Ravenna 10 is a running shoe that offers a resolve sole, 10mm drop and mild support. It uses the Brooks GuideRails system to provide said support when needed. In this review, I’ll look at the men’s edition, but there is a woman’s edition, too.

It has some cushioning, but not too much, and even more generous cushioning on the tongue. The inside feels silky smooth: I can happily go around in these without socks. It weighs in at 280g, just slightly above what the Brooks website promises. There is plenty of space in the toe box for my big toe.

After a month of running the shoe still looks in great condition, except for the inside of the heal, which has started to bobble. No splits yet and hopefully, it will stay that way.

Unfortunately, the Ravenna has one major drawback: it loses a lot of grip in the wet. If you are running in the rain, or even if the ground is damp, you tend to slip and slide all over the pace. Friends who run in Brooks report the same problem to me. This is super frustrating because it rains a lot in England and having to check the weather forecast every time I am going out in them is a chore.

In short, this is almost an amazing running shoe. I love it in the dry. However, losing so much grip in the wet means that this shoe ultimately gets the thumbs down from me I’m afraid.

Looking for running shoes with mild support? Consider the Brooks Asteria if you want a racing shoe with less cushioning, or the excellent Nike Zoom Span.

Last week, when Hyde Park Harriers took on Leeds parkruns, I took my GoPro along to document the trip. Here is the film I made.

If you are an age-group triathlete or amateur time-trialist, nothing will give you free speed like aero bars. In this video, I will discuss the pros and cons, show you how to get some onto your bike and give you some tips on how to get started with them.

Aero bars, also known as tri bars, allow you to get into a much lower, aerodynamic position. The downside is that your hands are miles away from my brakes, and closer together, so it can be a little intimidating to lose some control. They also take up a lot of space on your handlebars.

Comfort is a mixed bag. Most people struggle to cycle in the aero position. However, I found it about as comfortable as sitting up. If anything, it was slightly easier on my back.

Performance gains

The speed gain is substantial. Between Alltherorpe Classic standard distance triathlon in 2018 and 2019, I improved my bike split by 11:28. Of course, it could be that I was fitter. But comparing Allerthorpe sprint triathlon a month earlier, my power was 20 Watts lower, and yet my average speed was up 5%. So, more speed for less power.

Getting them on your road bike

You can buy clip-on aero bars for around £30. These bolt onto your handlebars so you can turn a standard road bike into a time trial bike. It is best to use a torque wrench if you can, as clamping them on to the recommended 8-10 Nm can be scary without one. It also helps to wrap some electrical tape around your handlebars to protect them.

Depending on your bars, they will be adjustable in different ways. Typically, you can adjust them by changing the angle and gap between them on the handlebars, by moving the bars themselves backwards and forwards and by changing the rotation of the armrests.

When you are getting started, you want to keep them fairly flat, as having them diagonally upwards in the praying mantis position will make you slightly more aero but will also make it more difficult to control the bike.

Riding on aero bars for the first time

When riding, there are several things you can do to get comfortable cycling with them. One option is to keep one hand on the hoods and put the other on the bars, then gradually lift the hand off the hoods. I am not a big fan of this because it is harder to control with only one point of contact than it is when you have both hands on the bars.

Another option is to find a small hill, say a 1-2% gradient, and go up it. This will allow you to put a lot of power through the bike while still going at a relatively slow speed.

You can also spend some time moving your hands between the hoods and the bars to get used to getting in and out of the aero position. As you get used to them, you will get used to having a little less control: this means sacrificing some of the small adjustments you would normally make in favour of a wider berth and leaning the bike a little more.

Ultimately, though, once I got comfortable, it just clicked. Like learning to ride a bike in the first place, once you “get it”, you should be away. Good luck!

The Wahoo RPM speed and cadence sensors are easy-to-install bike sensors that provide data by both Bluetooth Smart and ANT+ connectivity.

They are small and don’t use magnets, which is a massive improvement over the bike sensors that you have to fiddle around with to line up. They are easy to install, too: you take the sensor and insert it into its rubber housing then strap it around your wheel hub (in the case of the speed sensor) or cable tie it around your crank arm (in the case of the cadence sensor).

The battery lasts for ages. I’ve been using them for over six months now, and they still have plenty of battery left in them.

The speed sensor is a bit of a pain to install, though. You have to stretch out the rubber and spend ages trying to get your hands inside the spokes to hook it around the catches that keep it secure. Luckily, it only takes a few minutes, and you only need to take it off when you need to replace the battery.

The data seems mostly reliable, but I have seen some occasional spikes where an unrealistic speed is reported. I found the data slow on Zwift: anywhere from 3-10 seconds behind the power, I was putting down. Outside, it consistently responds within a few seconds on my Garmin head unit, so I think a large part of the problem is Zwift rather than the sensor.

In this video, I’ll show you both of the sensors, and I’ll also show you a close-up of me installing the speed sensor on my back wheel.

Garmin produces a range of heart rate monitors for triathletes. In this video, I’ll compare the HRM-Tri and HRM-Swim. I’ll also talk about Garmin’s new models, the HRM-Run and HRM-Dual.

Both the Tri and the Swim come in the Forerunner 935 triathlon bundle. The Tri is the go-to heart rate for everyday training. It has a stretchy strap that is comfortable so makes the perfect choice for running and cycling. It can also be used in the pool for short distances, such as pool-based sprint triathlons. Just make sure to give it a good rinse when done.

The HRM-Swim is specifically for swimming a pool. It has a non-stretchy grippy strap that is less comfortable but means that it won’t slip down when you dive into a pool or kick off from the side. It is also more resilient to corrosion from pool chemicals.

Both can record heart rate data underwater, although you will only be able to download it when you get out of the water. They both transmit over ANT+, so if you’re looking for something that does Bluetooth you need to look at the HRM-Dual instead. Or the Polar H10, which I have also reviewed.

The Stages Power L Shimano 105 is a single-sided power meter that replaces the offside crank arm on your bike. You pull off your existing crank arm and fit the Stages Power drop-in replacement to get some power measuring data.

Stages produce a full range of different versions for each groupset, so you need to match the correct one. In this case, my bike has a Shimano 105 groupset, so I needed that version. As it is the offside crank arm, chainrings are not important, but if you want the dual-sided one, you will need to match your chainring as well.

The beauty of them is that they plug in and go. You don’t need to change your pedals, and if you are comfortable taking it on and off, you could even swap it between bikes (if you had another with the same groupset).

The unit transmits on both Bluetooth and ANT+. In the past, there have been issues with drop-outs between Garmin and Stages. I haven’t experienced any of this; it has worked perfectly with my Edge 1030 and with TrainerRoad on my iPhone. I have had some drop-outs on Zwift, though, but I’ve had a lot of problems with Zwift regardless of setup.

Battery life is reasonable. It takes a 2032 watch battery which has lasted me about six months. The battery is easily accessible so looks simple to change.

Without calibrating it against another power meter, it is difficult to say how accurate it is. But, on the turbo trainer, it has worked like a dream. Outside has mostly been fine, too, although I have occasionally got spikes of power way higher than I would expect.

I’ve also had a bit of squeaking. Whether it is because the crank arm has come loose or because there is an issue with the bottom bracket on my bike is not clear.

The Shimano PD-M530 is a dual-sided SPD bike pedal. SPD is Shimano’s two-point mountain bike cleat but is also a favourite for commuting or those who are new to clipless pedals because it is easier to clip in and out of than the road version, SPD-SL.

The M530 has SPD cleats on both sides. This means that you do not need the pedal to the be the correct way up; you can push your foot down, and it doesn’t matter what side it is on.

The pedal comes with the standard dial to make it easier or more difficult to clip in and out of. Being dual-sided, though, means that you have two dials on each pedal which means you have to set the tension to how you like it four times in total.

They are mostly black, which should match standard crank arms. They have a larger surface area than other styles of SPD pedals, such as egg beaters, which makes it easier to find with your foot. You won’t be able to use them as flats, though, as your foot always makes contact with the cleat. And, having a larger surface area, they are heavier than other types.

If you like the look of these pedals, you may also want to consider the Shimano PD-EH500, which is similar but has a flat side as well as an SPD side, allowing you to choose between clipless and flats. In the video, I’m actually demoing the EH500, but only on the SPD side, which is identical to the M530.

In this video, I’ll attempt to change the stem on my bike. The stem is the piece that holds your handlebars to your steerer tube. You may want to use a bigger or smaller stem to dial in the perfect amount of reach (the distance your handlebars are to your saddle).

I’m not calling it a tutorial because I have never done it before, so who knows how it will turn out!

I’m using my Voodoo Limba cyclocross bike. I made the rookie mistake of buying a frame that was too big for me and so I needed to reduce the reach. I moved the saddle forward to put it into a racier position, using my race bike to match the geometry. But I also needed to swap out the 90mm FSA stem for a 70mm stem. Luckily, FSA does such a step, so it should just be an easy swap-out swap-in job.

The first step was to take off the reflector which was blocking access to the bolts holding the stem’s front plate in place. I then loosened these a little at a time to avoid putting too much stress on any bolt. Once the faceplate was off, I let the handlebars dangle down. I had my bike on the turbo, rather than in a stand, so there was no chance the forks would drop out.

Next, I removed the dust cap from the top of the stem and then loosened the bolts holding it onto the top of the fork. Once this was done, it slid off and allowed me to put the new stem on. Then it was merely a case of reversing the procedure.

Getting the new stem in the correct position is a tricky one. The handlebars need to be both in the centre and at the correct angle, and it took me a while to get them just right. After that, I could tighten up all of the bolds, including making sure that the stem lined up with the forks and front wheel.

In this video, I’ll review the ROKA men’s SIM Pro II buoyancy shorts. It’s the full thing: I’ll take you from the unboxing into a long-term review where I report back on them after a month.

Buoyancy shorts simulate the position in the water that a wetsuit gives you. This means you can practice your open water swimming practice in the pool. This could be a lifesaver for triathletes who don’t have a local lake to swim in and thus only get to practice their open water swimming in triathlon races.

I spoke to ROKA about the difference between the Elite and the more expensive Pro version. They’re very similar but the Pro version is slightly more adjustable and slightly more buoyant, so will give you a slightly better position in the water.

Are they race legal? Not really. They count as a wetsuit. So, you can’t use them in a pool-based triathlon. If it is an open water event and wetsuits are allowed, you could use them. But, in that case, you probably want to go with a full wetsuit instead. So, they’re really intended for training.

They are made of neoprene, which is the same material as a wetsuit. Basically, it feels like they have cut a section out of one and added a drawstring. I was worried about tearing it, but so far, so good.

Yesterday I wrote about the duathlon I took part in at the Brownlee Centre. I recorded the bike section on my action camera and I have overlayed my speed, power and heart rate onto the video. It’s predictably dull, but I have added some commentary over the top to make it less dull lol. In my defence, this isn’t why I bought an action camera.

The hyper smooth video does a good job, although I find it a bit weird. The background stays fixed in position as everything else dances around. It looks a bit unnatural but does produce something that is easy to watch.
