I live in a very hilly area, so all my runs contain hills. Therefore, I prefer training to use my heart rate, running a bit slower uphill and faster downhill. The daily training suggestions however always only use a pace, although it shouldn't be difficult at all to translate them to a heart rate (e.g. today my recommendation is running at threshold pace, which could easily be translated to threshold heart rate). Is there an option I missed or can I put in a feature request somewhere?
