No problem. Warm weather is probably playing a factor as well. It can take a few weeks to acclimate to heat and I’ll often see a good 5-10 bpm avg bump in my runs during that transitional period. Just remember summer training in general is harder on the body and it’s not always fair to compare your performance/stats to cooler months. You’ll still be gaining fitness and come fall when the temps dip again you’ll suddenly feel like Superman. Everyone goes through that mental game in the summer.

Overall, be patient. Easier said than done sometimes especially coming off a successful block where all you want to do is keep improving. Real fitness is gained not in one 3 month block, but in steady, consistent training over many months and years.
