20bpm above what I was previously training at. 

I changed the screens of my running watch so my heart rate wasn't on the main screen as the psychology of knowing how fast it was going really made my keto-training runs quite tough. 

Can't wait for it to get back to normal. 

I wonder if this temporarily increase in heart rate has any benefits I could reap in the future...
