running 38:09 [4] 8.0 km (4:46 / km)
run at the clash, but used my heart rate monitor and did it as fartlek training (with pieces of 800m fast pace, alternating with 500m slower pace and the last 1.5km i did at fast pace) i was aiming to be in my 80% zone for fast pace and 70% zone for slower pace. my average for my faster pace work was 169 bpm and for slower pace was 160 bpm. i'm a bit annoyed because i really tried to push myself in the fast pace work and slower in the recovery so but overall there didnt seem yo be much of a difference between my two heart rates. although they are in my right zones, 169 bpm is 83.4% and 160 bpm is 77.9%, the gap between them is a bit close. im gonna do more interval work coz i found it more tiring and benficial then a steady run, which i would actually usually have done in a quicker time. for the last 1.5km i picked the pace up and got into my 90% zone (180 bpm)
