Running definitely gets easier when you lose weight

Compared to when I was 168cm and 63kg last year, running and training with an average monthly mileage of nearly 200km
Now at 168cm and 55kg, I couldn't train much because it was difficult,
but the records I'm getting now are better than before.
To be honest, I was really worried about yesterday's time trial because I hadn't trained much and feared I'd perform worse than my previous record... but I think losing weight helped me get a good result.
From now on, instead of obsessing over long distances except for when I'm doing 30km+ long runs, I think I should focus on training like build-up running or adapting to marathon pace.
Also, I'll be going to Namsan Hill during the holidays haha
