Absolutely superb. ATW staff and volunteers at another level and make every entrant feel safe and comfortable. This event is top drawer in every way, impossible to fault, but the staff were the highlight. Routes were safe despite not being road closed. It was also a lovely day, thankfully a member of staff had some sun cream for me, a lovely Scots lady and slathered me as it was red hot during the run. Thoroughly recommended and 100% better than Ironman, who are pants unless you are an elite pro. They just want your money. ATW want you to enjoy the whole experience and I did. Thank you ATW. Neil
