Balls out HR?

[Valiant]

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.

I can only get to about 195bpm cycling, no matter how hard I try, but I can get to 205bpm running.

So I'm not in any chance of a heart attack or something?

That makes it sound as though you're trying.

Not trying to give myself a heart attack, I was trying to see how far I could push it on the bike before the bike or my legs gave out. At that speed I was spinning out I need to get back out on Freyja.
