Figure i may as well put up the graph of my heart rate and the altitude from the race!
You can plainly see the 3 climbs on the race for each lap. First Little climb on the bike is Witches Hill, then the big long one, then the last quick one before you head back onto the straight away to the turn. You can also see the little blip on the run that was the Stairway to Heaven!
Power graph above gives a decent view on my speed and power output on the climbs. Average power was definitely down on the climbs on the second lap but average power for the first lap wias a nice easy 204W and a 196W for the second lap so pretty consistent for the whole thing. Happy enough with that! Nothing amazing but i stayed damn close to the aim of 200W for both laps
