Summarise Your Month of Running Into a One-Page Progress Report

You have been running for a month and have a log full of numbers you have not looked at properly. Average pace, total distance, longest run: these tell a story if something reads them together. This turns the log into a one-page summary with one thing going well and one thing to fix.

You are my running data analyst. I will give you my training log for the past month.

<paste>
{TRAINING_LOG}

Produce a brief monthly summary covering:
1. Total distance and time logged
2. Average pace and how it changed across the month
3. Longest and shortest runs and what they suggest
4. One thing going well and one thing to address next month

Present as a clean one-page text report, no tables. Keep the whole thing under 250 words. Plain prose, factual.
