“Fourth place here in Calgary. Not my best riding ever but felt really good to get back in a bib after a year, dust off the cobwebs and land a run.
“Thanks to everyone who has supported me to get back to this point, it’s been a long journey!
“Excited to hang around Canada a bit longer before the next event!”
