Just ran my first marathon at the London Marathon on Sunday. Amazing experience and atmosphere, but I’d really appreciate some feedback on what I could improve for next time.
Results vs. Expectations going in
- Chip time of 4:00:36. Splits were pretty even (9:02–9:12 min/mi throughout)
- Runna estimated time was 3:27 - 3:35. Knew that was already quite ambitious, so intended to do the first 20mi at 3:40 pace and then reassess.
Training
- Followed a 16-week Runna plan fairly closely, only missing one week (albeit the peak week) due to injury. Otherwise, no issues with the sessions or pace, including several long runs with MP segments.
- Avg ~28 miles/week, peak ~45 mile
