Today was sprints day these all out efforts for a minute are exhausting but they help build my explosive power and fast twitch muscle fibres, otherwise known as type 2a and type 2b muscle fibres.
My sprints today were really hard work! But I am noticing that I go further during my sprint which is great as it means I am getting faster.
Although heart rate can be effected my sleep, hydration and temperature when I do my sprints I am looking to work in my threshold and vo2 max zones.
I have a rest day tomorrow and then on Saturday my first race of the season. A sportive in West Sussex, I am looking forward to racing my new era and putting all the hard work over the winter to the test.
Check back on Sunday for my race report.
