Last weekend the strongest post-2000 runner Feng Peiyou set a new Chinese marathon record at the Tokyo Marathon with a time of 2:05:58. After the race, with Feng Peiyou's authorization, PaoYe Big Bang obtained his sports-watch data from this Tokyo Marathon — let's take a look at what it reveals. Beyond massively breaking the national record and becoming the Tokyo Marathon's overall "Asia's best", Feng Peiyou's outstanding performance has ushered Chinese marathon running into the era of average paces under 3:00 per kilometer. During the race, Feng Peiyou spent 85% of the time in the aerobic power zone with paces between 2:48 and 3:02 per kilometer. His average heart rate was 169, with a maximum of 187. His average stride length reached 1.86 m, very close to the level of top African runners. Average cadence was 182 spm, so there is room to improve — perhaps this is where Feng Peiyou can find further speed. In terms of splits, Feng Peiyou was fastest in the first two 5-km segments, clocking 14:48 and 14:51 respectively; his speed then dropped, and except for the 30–35 km segment which returned to 14:52, all other 5-km segments were slower than 14:55. Comparing Feng Peiyou's data from this record run to He Jie's when he set the previous record, Feng was 43 seconds faster in the first half and 16 seconds faster in the second half — showing that the excellent first half laid the foundation for the large record improvement. Who do you think will break the national record next, and what time will they run? #PaoYeBigBang #marathon #FengPeiyou #RecordBreaking #HeJie
