【サブ3.5練習】35℃炎天下で初インターバル走(1,000m)したら地獄でした

02:25 First 1,000m Challenge 04:41 Quite a Long Rest! 05:45 Second Challenge! 09:21 Future Challenges for Sub-3.5 Interval Running I attempted my first ever interval run on a track in the scorching summer heat of 35℃! I aimed for a sub-3.5 marathon with 5 x 1000m intervals, set at 04:30/km. The result...? I struggled greatly with the heat and difficulty, which were far greater than I imagined. This run revealed challenges in pacing and the direction of future training! Please watch as I share the harshness of summer and my current reality.
