The mHealth Grand Tour Team

From the moment I sat down to dinner with my new team mates the night before the tour, I knew this was going to be an unforgettable experience. Across from me was Nenad, a type 1 athlete from Zagreb who had completed a triple ironman (which consists of a 11km swim, a 540km bike ride […]


Keeping continuous glucose monitor (CGM) sensors stuck on properly can be something of a challenge. Showering, sweaty gym sessions, swimming and the general rough-and-tumble of daily life all conspire to help remove your costly CGM sensor from your body. But how best to keep them from working loose? Kinesio tape is a popular way of […]

Week 1 Training gets off to a good start, with a 45min easy spin session on Monday and then two 90 minute sessions on Tuesday and Thursday – 90 mins at 184W with 3 x 8 min at 274W (5 min RBI). I found them ok – not easy, but not brutal either. In place […]

According to The Time Crunched Cyclist training plan, in order to train as effectively as possible one needs to determine at what intensity to train. For me this was one of the big motivators for starting this training plan – were all those hours I as spending out on my bike having the effect I […]

This wouldn’t be a blog about technology without a thorough discourse on the technology involved. But before going through the design spec, let’s take a look at the user requirements: Only capture information once and automate as much as possible See calorie intake and calorie expenditure side-by-side to ensure I was eating correctly (after a […]

Over the past ten years I found myself working increasingly long hours for an investment bank, but always tried to squeeze in as much training as I could. The training was mostly a mix of circuits and strength training with a personal trainer, plus a couple of bike rides a month. It worked well. The […]

With the prevalence of mobile computing, self-monitoring and Big Data technologies, new approaches to the management of type 1 diabetes management might be possible. Take for example the administration of insulin in type 1 diabetes when eating pizza. It is often reported that rather than taking one single bolus insulin dose when eating pizza, the insulin […]

Figure 1 - exercise and total daily basal insulin usage

1. Introduction In Type 1 diabetes, exercise has an effect on blood glucose levels. In general, during periods of low to moderate intensity exercise, blood glucose levels will drop. To counteract this, either insulin is reduced or carbohydrate intake is increased. Moreover, it is often reported that this effect may last for up to 24 […]

At the start of the project I thought I would be spending all of my time using Hadoop and other Big Data technologies to analyse my data. The conclusion that I rapidly came to is that if you don’t have huge amounts of data then Hadoop is probably not the best option. Once I have a […]

As part of my project to correlate exercise and insulin usage in type 1 diabetes I need to get hold of my blood glucose and insulin usage data. I use an insulin pump with an embedded continuous glucose monitoring (CGM) sensor. Periodically I upload all the data from the pump to Diasend. Diasend is quite a […]
