My best known marks are organized by discipline, from 300 m to the marathon. Races, time trials and training efforts keep their settings; same-pace comparisons carry an asterisk and show the original distance and time. The results come from different years. The notebook keeps the 800+ point goal profile I am working toward now.

Points use the men's columns of the 2025 revised World Athletics tables, with the lower score between thresholds. A time links to its source; the date leads to the account or activity. Pace is rounded to the nearest second per kilometre; points use the original time or unrounded conversion. Dates marked UTC retain an unresolved local day from the export.

Personal bests by discipline

* Same-pace comparisons retain the original distance and time; they do not establish another completed race or finish split. Sofia's short-course length remains unresolved. † Short training points are conditional on the unestablished timing method. The measurement notes keep these limits and the scoring details together.

Race history

The full recovered race history follows. Original result times, course labels, placings and the dated accounts remain here, including earlier marks that were later improved. Chip times govern road results; gun times stay separately labelled.

Measurement and score notes

* A comparison keeps the original effort's average pace over the named discipline. The mile scales the documented 1600 m in 5:08 to 1609.344 m; its comparison is 5:09.80, worth 388 points. The road comparisons scale longer source distances down, using full elapsed time for recordings. They do not establish an additional completed race or finish split. Displayed comparison times round up to the event table's precision. Sofia's course length remains unresolved: 291 points uses the official results' 10.5 km label; 42:04 over 10 km would give 205.

The 15 km time sums the first fifteen 1 km watch laps. Its distance is recorded by the device. The 20 km comparison also uses a GPS distance, without a claim of a measured course. The half-marathon best is the reported 1:36:57 training split within the April 24.64 km outing, replacing the earlier whole-run pace comparison; the separate October 21.10 km in 1:38:14 remains in the dated account. The 2000 m and 3000 m training paces both round to 3:26/km; their unrounded difference is 0.3 seconds/km.

† Short training points compare the written mark. The short efforts' timing method, start and wind have not been established. Official comparison of hand-timed sprints at 300–400 m requires adding 0.14 seconds; for example, a hand-timed 56.05 would be scored as 56.19, giving 531 rather than the literal mark's 537.

Park-course labels

¹ North Park's current result page says 6.0 km. The organizer'sreport published on 7 December 2015describes the same short event as 5 km. I retain that contemporary label; no exact historical course measurement has been recovered.

The Sofia short-course label

² The 2020 results say 10 km; the 2021 results say 10.5 km, while that edition's map advertises 10 km. I remember the same route in those two years. The exact measured length of the separate short course remains unresolved, so the 42:04 is not listed as a certified 10,000 m best.

The 2017 instructionsdescribe one short lap of the older four-lap marathon route, starting outside Vasil Levski National Stadium. The later start wasBattenberg Square; the 2021 mapsshow a two-lap marathon and a separate shorter loop. Dividing the marathon distance by four would not recover the later short-course length.

Training references

Other sprint distances and interval lengths stay with the dated training record. The discipline table above keeps the selected best marks. Other dated references stay with their accounts: thechildhood neighbourhood effort, thereported 2 km in 2020and thecurrent 2000 m trial. Their dates, measurement limits and roles in the story remain visible there.

Repeated workouts have a different comparison: times, count and recovery together. See the 2021 900 m series,mixed-rest fast work in 2022and current protocol comparisons.
