Thought we needed a thread for this - there are various bits and pieces scattered about on other threads.
Tuesday I did 6x iterations of Palgrave Hill - a convenient nearby hill that has a 40m gain and steepens toward the top for that extra kick. All I need to do is maintain 18km/hr all the way up, and try not to throw up. My heart rate is usually 100% for the last 20s or so - around about the 185 mark.
Now - I just got back from only my second ever 2x20 session. The best part about it? Stopping
.
The second best part is the endorphine rush afterwards. Oh my...
Anyway some useless facts:
Outward: 172bpm, 9.9km, 28.8km/hr
Return: 175bpm, 10.2km, 30.1km/hr
Ooh... jelly legs.
