Frequently Asked Questions
How do I choose a realistic marathon goal time?
The most reliable formula: recent half-marathon time × 2.1 (Daniels) or × 2.08 (Riegel for trained runners). Adjust slower if your weekly long run is below 30km, the course has hills, or race-day temperature exceeds 18°C. Use the race time predictor to compute multiple methods at once. The goal time guide covers when to ignore the formulas.
Should I aim for a negative split or even pacing?
Even pacing is the published winner — Hauser 2014 analysis of finisher data shows the fastest age-group times come from runners whose halves differ by less than 2%. Pure negative splits (second half faster) are statistically rare in marathons (under 15% of finishers). Practical advice: run the first 5K 5-10 sec/km slower than goal pace, hold goal pace 5K-32K, then race the final 10K. Use the pace band generator for kilometer-by-kilometer targets.
What times do I need for a Boston Qualifier (BQ)?
For 2026 Boston Marathon, qualifying standards range from 2:55 (men 18-34) to 4:25 (men 65-69) and 3:25 (women 18-34) to 5:00 (women 70+) — but actual cutoff times run 5-7 minutes faster than the standard due to oversubscription. Aim 5+ minutes under the published standard to feel confident. Full table and strategy in the BQ qualifying guide.
Is the run/walk method legitimate for marathon racing?
Yes — Jeff Galloway's run/walk method has 30+ years of finisher data showing it can deliver faster times for first-timers and masters runners than continuous running. The mechanism: walk breaks reduce muscle damage and let glycogen and lactate clear during the run portions. Suggested ratios in the run/walk marathon strategy guide — 4:1 (run/walk minutes) is a common starting point.
What should I eat in the 24 hours before a marathon?
Carb-load to 7-12g/kg body weight in the 24-36 hours before — for a 70kg runner that's 490-840g of carbs total. Dinner should be high-carb, low-fiber, low-fat. Race morning: 100-300g carbs 2-3 hours before start (oatmeal, bagel, banana, sports drink). Avoid anything new, anything fried, and anything you don't normally eat. Detailed timeline in the race day preparation guide.
How do I pace a hilly marathon course like Boston or NYC?
Add ~5-10 sec/km to flat goal pace on uphills, take ~5 sec/km back on downhills (don't try to make all of it back — descending hard at marathon pace destroys quads). On Boston specifically, the first 16 miles are net downhill — discipline yourself to NOT bank time, then prepare for the Newton Hills (miles 17-21). The hilly marathon training guide covers course-specific pacing patterns.
About these guides
The marathon training plan you spent four months executing decides about 70% of race day. The remaining 30% — goal pace selection, course-specific strategy, fueling timing, what you do in the bathroom line at 6:45am — is where most runners lose 10-30 minutes against their fitness. Pacing decisions made in mile 2 cascade to mile 22; choosing a goal that's 5 seconds per kilometer too aggressive turns the final 10K into a death march.
This category collects 6 guides for the racing side of marathoning: how to pick a realistic goal time from your recent training and race data; how courses with 200m+ of elevation gain (Boston, NYC, Athens) need different pacing than flat city marathons; the run/walk method that lets first-timers and masters runners finish strong; the BQ qualifying time tables for runners chasing Boston; and the hour-by-hour race day checklist that removes guesswork from the morning of the race. Each guide pairs with the relevant calculator — pace bands, course-adjusted predictions, or the BQ percentile estimator.
If you have a marathon date set, work backwards from race day. Start with the race-day checklist 2 weeks out, then read the pacing strategy guide to confirm your goal. If your race is hilly, the hilly marathon training guide should be added 8-10 weeks before race day. BQ chasers should read the qualifying standards page first to set the right target before committing to a hard plan.
