Running a marathon is already a great feat. For Adrian Lehmann, professional marathon runner from Switzerland with several inspiring results in World Athletics, it has a more powerful meaning as he aims to represent his country during some of the most important marathon races in the world. On April 23rd, Adrian competed in the Zurich Marathon with an impressive finish time of 2:11:44, earning the 2023 Swiss Champion Title. Let’s take a dive into Adrian’s data leading up to this achievement.

Adrian’s watch: COROS PACE 2

Analysis software: COROS Training Hub

Preparation For The Race

Adrian first focused on building up Base Fitness for the first 2 months this year before diving into specific marathon training prior to Berlin Half-Marathon early April. Then, he tapered through the month of April before Zurich Marathon on April 23rd.

We can see with the Intensity Trend metric in the photo below that Adrian dropped below 0 during taper. This is a good sign as it means his current training was not as hard as what he is used to.

2023 Zurich Marathon Analysis

Adrian approached the Zurich Marathon with a competitive mindset. Looking back at his data from the race, we can notice a very consistent pace throughout the race. In fact, he completed the first half in roughly 1:05:51 and the second half at around 1:05:53.

COROS Education: Athletes can look back and analyze their race through the Training Hub desktop software.

Diving deeper into his race analysis, we can notice that Adrian maintained a race pace at 3’06″/km while his threshold pace was closer to 3’00″/km. Elite marathon athletes have the ability to complete a marathon closer to their threshold pace in comparison with amateur runners.

Additionally, Adrian maintained an average HR of 153bpm, just a few beats below his Lactate Threshold. Getting too close to his threshold HR would have lead to accumulated fatigue and potentially slowing down near the end of the race.

COROS Education: Athletes have access to training zones both for HR and Pace in the Training Hub.
