[19] In August 2017, Soh courted controversy when he was given a formal warning by the Singapore National Olympic Council (SNOC).

[29] However, Soh was not selected to compete in the 2019 SEA Games by SNOC to defend his marathon gold despite being nominated by SA.

[32] He issued a challenge to all Singaporeans to clock a sub-7 timing; anyone succeeding would receive $700 and 700 bottles of Pocari Sweat paid by Soh.

[9] On 17 June 2022, Soh would rewrite his 2014 national record for the 10,000m track event with a timing of 31:12.05 at the England Athletics' Championships.

[38] On 25 March 2023, The Straits Times reported that Soh had been selected for the 2023 Southeast Asian Games by the Singapore National Olympic Council, bringing an end to years of dispute between the two parties; this allowed him to compete in the 5,000m and 10,000m events.

That was just 4 seconds short of his own national record and clinched silver in the 10,000m, ending Singapore's 40-year wait for a medal in the event.

[43][44][45] On 10 June 2023, Soh was not selected for Singapore's 2022 Asian Games line-up (delayed due to COVID-19 pandemic), after the SNOC claimed that he had made 'disparaging' remarks.

These comments were allegedly made in relation to the previous dispute over the credibility surrounding Ashley Liew's 2015 “act of sportmanship”, as well as a current teammate, religion, and use of vulgarities among others.

Despite Soh deleting the comments he made online, the SNOC upheld their decision, stating that the "behaviour does not commensurate with his apology given".

[48] On 8 August 2023, Soh set a new Singapore record in the 5 km road race, finishing 3rd in the Sri Chinmoy Kangaroo Hop 5k in London.

In the same race, Soh passed through the 10 km mark with a split timing of 31:39, breaking the previous record of 32:10, co-held by Mok Ying Ren & Jeevaneesh Soundararajah.

On 13 September 2024, Soh broke his own 5km road national record by 7 seconds, running 15:08 at the Podium Friday Night Under The Lights 5K at Battersea Park.

[51] This was made even more notable be cause Soh had just turned 33 years old and graduated with his law degree in the week leading up to this new record.

[56] In 2021, Soh signed a four year endorsement deal with Under Armour, an American apparel brand, to be part of its global athletes programme.

[58] In October 2018, Soh disputed fellow runner Ashley Liew's version of events surrounding the 2015 SEA Games marathon.

[7][60] 3 other witnesses, including Filipino runner Rafael Poliquit Jr. who was also in the same race, backed Soh's version of events in the media.

[70] A debate ensued over whether a potential medallist should be barred from being a national representative due to personal conduct issues.

[77] The case concluded on 8 June 2022, with District Judge Lim Wee Ming accepting Malik's defence of justification in defaming Soh.

[78] However, Malik himself admitted to taking down the Facebook post in question, because they were not "in good taste", and that the words he had used painted a "negative" and "unflattering" picture of Soh.
