Rojee, could you provide more information about grabbing the FIT file from the watch? Also, what kind of analysis do you do locally?
... Sorry, what type of file is it? Just a CSV?

Obtaining the file is as easy as connecting the cable to the device and plugging in to a USB port and accessing the mounted drive

I'm building a running analytics app, which is really just for myself but if it turns out to be any good then I'll might turn it into a SaaS. Target market would be for fairly decent amateur runners (e.g. 2:20-2:30 marathon) but not good enough to be pro. The pros have awesome tools but sadly most are not available for us mere mortals but I can build some of them! Example features:
1. The strava GAP model doesn't fit very well for me. So I've made my own. I update the model each month too.
2. I've also built a wind resistance model which works quite well. I'm trying to do the same for surface types, heat and humidity as well.
3.Using adjused pace data I built a pace/duration model to estimate critical speed and this model forms the basis of tracking progress over time. Clearly most training wont be all out efforts, so I also estimate race performances based upon current fitness as well. E.g. if you ran X speed for Y time at a sub maximal effort then you can estimate what a maximal effort would be based upon the remaining aerobic and anaerobic power. From reading sports science literure, this is the most advanced way to track performance at the moment. The actual model I use is called an omniduration model [1].
4. I also have build some other models, e.g. Daniels running formula, which can be used but I don't find them to be as useful as the omniduration model.
5. I'm also trying to model how a workout will effect your fitness. Where it's base/aerobic, threshold, VO2max or an anaerobic effect. Then, the idea would be to look at future training performance to assess whether the model was correct. This was you might be able to determine which types of sessions result in the best outcomes for you.
