I've been looking at the intensity of my training over the last 12 weeks. It's really interesting to see how different training protocols can affect fitness. I created this chart to show the effective effort vs duration across different exercises. At a glance there are a few interesting things to take note of.

For instance because most of my cycling is commuting between home and work and it clusters closely together while my running is much more distributed across duration and effort. All the quadrants are relative to their own activities so it can look like there's an even distribution across all four, but in fact running has the highest by a large margin.
