Sub 1:30 Half Marathon Pace Chart & Training Guide

Training for a Sub 1:30 Half Marathon

Running a Half Marathon in under 1:30 requires a pace of 4:16 per kilometer (6:52 per mile). This is a realistic goal for competitive runners who commit to a structured training plan over 8-16 weeks. Your weekly mileage should be in the 70-95 km range, with three quality sessions per week: one interval workout, one tempo run, and one long run. The key interval session is 4×3km @ 4:10/km with 90-second recovery jogs. Your tempo runs should be 40 min @ 4:15/km, building the lactate threshold endurance you need to hold race pace when fatigue sets in. Long runs should be 25-30% of your weekly volume, run at a comfortable pace 60-90 seconds slower than your target race pace. Consistency matters more than any single workout. Missing one session is fine, but missing a full week sets your aerobic base back by roughly two weeks. If you are coming off a break, add no more than 10% weekly mileage per week to avoid injury. At the elite level, VO2max development is your primary limiter. Include hill repeats (8×90sec at maximum effort) once every two weeks to build power without the joint stress of flat sprints. Double-run days, with an easy morning jog and a quality afternoon session, accelerate adaptation when weekly volume alone is insufficient. Mental rehearsal matters at this level: visualize the race course, practice your exact fueling strategy in training, and run at least two dress rehearsals at goal pace. Recovery is training too. Sleep 8+ hours, prioritize protein within 30 minutes post-workout, and schedule a full rest week every fourth week. Sub-90 half marathon is an elite target requiring sustained 4:16/km for 21.1 km. The difference between 1:31 and 1:29 often comes down to fueling. At this intensity, your glycogen stores deplete around 75 minutes. Take a gel at km 7 and another at km 14 to maintain blood sugar levels for the critical final 7 km. Practice this fueling schedule in every long run above 16 km.
