# From 3:01 to 2:06: Why I Built TrainPace

TrainPace is built and run by Alex, a software developer and self-coached runner in Vancouver, BC. He built it during the training block that took his BMO Vancouver Half Marathon time from 3:01:00 (May 2024) to 2:06:00 (May 2025) — 55 minutes faster, after 24 weeks of structured training.

**The numbers**

| Race | Time | Average pace |
| --- | --- | --- |
| BMO Vancouver Half Marathon, May 2024 | 3:01:00 | 8:35/km (13:48/mi) |
| BMO Vancouver Half Marathon, May 2025 | 2:06:00 | 5:58/km (9:37/mi) |

## What changed

- One long run per week at Zone 2/3 intensity
- One speed workout per week: tempo runs, intervals, and threshold work
- Easy runs about 2 minutes per kilometer slower than race pace
- A km-by-km race plan built from the course elevation profile
- A fueling plan from the TrainPace fuel planner: it said 3 gels, and 3 would have been enough

## Why TrainPace exists

- Pace calculators were buried in ads
- Switching between min/km and min/mile was a pain on every site
- Strava does not offer a pace calculator in its mobile app
- Elevation analysis meant staring at a static chart instead of seeing grades and climbs
- There was no simple way to work out how many gels a race needs

TrainPace is for self-coached runners who want to train with data without paying for a coach. Every calculator is free, needs no account, and uses published methods: Daniels & Gilbert VDOT formulas for paces and race predictions, grade-adjusted pacing from real elevation data, and carbohydrate targets from sports-nutrition research.
