So this morning I made the half hour journey out of Athens to the Equestrian Centre, where the horse riders are getting ready for the start of their competitions on Sunday.
I caught up with Sarah Cutteridge, who'll be riding her mare The Wexford Lady in her Olympic debut.
Cutteridge is a former Junior and Young Rider National Champion. She was fifth in Burghley in 2003 and eighth at Badminton this year.
She told me how the horses -- and riders -- are coping with the sweltering Greek conditions.
Here's my first Olympic videoblog.
It's 2'39" long and is a 2.3Mb .wmv download. Let me know if there are any problems downloading it.
