I haven't been on the bike in a week due to being abroad so this morning I was feeling quite fresh on the bike and well just went for it. The whole pre-commute ride was noticibly faster and on the embankment I managed a top speed of 34mph for a few hundred yards, head down going balls out, and 209bpm
Is my HRM broken? Granted it's a cheapo one but it's done me proud so far. My highest bpm previous to today was 186, with an average cycling rate of 160 with a resting hr of 68. My heart was trying to pop out my chest but I did have the biggest grin on my face.
