Video of Ben’s 5.55 I saw on a news archive website that I uploaded to youtube
Ben setting a then-WIR 5.55 for 50m at the 1987 Ottawa Winternational Indoor Games (Fri 31 Jan). As we know he would go on to run a WIR 6.41 over 60m at the 1987 World Indoor Championships in Indianapolis, IN, USA (Sat 7 Mar). Later that summer he would break the WR in the 100m outdoors at the 1987 World Championships in Rome, ITA with 9.83 (+1.0) and the later Biomechanical Study (not the Fast study) split-time segment data showed Ben reaching the 50m and 60m segments in 5.55 and 6.38 respectively, so comparable with his Indoors times achieved with zero wind
