Tymewear shirt and app paces your run

Tymewear are developing a running shirt and app that works out your threshold pace and helps make your runs more effective at improving your performance. On the website they are not giving much away about the technology, but it looks like a heart-rate monitoring shirt, though they have opted for a rear fitting pod for the battery and electronics, similar to the way companies like Catapult position their GPS sports trackers.
