Can anyone out there help me? The past few years I have been getting early season hayfever, which I have got right now. I have tried Boots All Day (loratadine) and Benadryl(acrivastine), each with partial success symtpom-wise. I don't mind which one I take, but I don't want it to affect my running and in particular the FLM race itself. Does anyone have experience of these medicines as a runner, or is there something else I should try (particularly for early season hayfever). Thanks.
