Training objective: 2 hours at very hard effort, with the heart rate at 155-165 bpm's and the last half hour as hard as possible. Bit of ENE and E wind against @ 11-20 km/hr, but happy with the result. Had to brake to avoid a potential collision at the 48 km mark. 2 KOM’s (which I held previously - so I improved my times on these 2 segments), plus 24 new personal records (2 in the top 20, 1 in the top 25) and surpassed my goal of doing the 61 km circuit in 1 hr 45 minutes – I did it in 1 hour 43 minutes 52 seconds. Also new personal record for 40 kms – did it in 1 hour 4 minutes 46 seconds. Not bad considering wind and no peloton benefit. Strava estimates my watts/kg for this ride as follows: 1 minute: 4.85 watts/kg 5 minutes: 4.38 watts/kg 20 minutes: 4.06 watts/kg 1 hour: 3.48 watts/kg Used the lap/split function, so lap 1 is the first 60 minutes, lap 2 is the 2nd hour, and lap 3 is the cool-down.
