Source-derived summary

Robert Kwemoi Chemosin (born 1 February 1989) is a Kenyan long-distance runner who competes in half marathons. His personal best for the event is 59:19 minutes. He is managed by Gianni De Madonna.

He first began competing outside of Kenya in 2012. He was the winner of the Udine Half Marathon in a personal best of 60:23 minutes that year, runner-up at the 15 km du Puy-en-Velay and fifth at the Giro al Sas.

He competed extensively over the half marathon the following year. He was runner-up to Wilson Kiprop at the Roma-Ostia Half Marathon in March, running a time of 59:19 minutes which would rank him sixth globally that year. Later that same month he was runner-up at the Stramilano, but his following outings were less successful, finishing outside the top eight in Yangzhou, Lille and Delhi. He acted as a pacemaker for the 2013 Frankfurt Marathon.

Chemosin's strong personal best from 2013 earned him a place for the 2014 IAAF World Half Marathon Championships, but he was the worst performer among the Kenyan team, finishing in 24th place more than two and a half minutes behind fellow Kenyan and race winner Geoffrey Kipsang Kamworor.

The current lead gives the account dated anchors—1989, 2012, 2013, 2014—that can be checked directly. The linked authority record independently contributes the date 1989-02-01. Its value is orientation rather than verdict, with Robert, Chemosin and Kenyan providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Robert Chemosin”, the useful work is to connect “kenyan long-distance runner” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 28, 2026. The linked authority identifier is Q19281860. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989, 2012, 2013 and 2014.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
